Simon Willnauer dc659feeb4 Add a setting to disable remote cluster connections on a node (#23005)
Today either all nodes in the cluster connect to remote clusters of only nodes
that have remote clusters configured in their node config. To allow global remote
cluster configuration but restrict connections to a set of nodes in the cluster
this change adds a new setting `search.remote.connect` (defaults to `true`) to allow
to disable remote cluster connections on a per node basis.

Jay Modi 7520a107be Optionally require a valid content type for all rest requests with content (#22691)
This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.

The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.

As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.

In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.

See #19388

Nik Everett dacc150934 Expose multi-valued dates to scripts and document painless's date functions (#22875)
Implemented by wrapping an array of reused `ModuleDateTime`s that
we grow when needed. The `ModuleDateTime`s are reused when we
move to the next document.

Also improves the error message returned when attempting to modify
the `ScriptdocValues`, removes a couple of allocations, and documents
that the date functions are available in Painless.

Jack Conradson 3d2626c4c6 Change Namespace for Stored Script to Only Use Id (#22206)
Currently, stored scripts use a namespace of (lang, id) to be put, get, deleted, and executed. This is not necessary since the lang is stored with the stored script. A user should only have to specify an id to use a stored script. This change makes that possible while keeping backwards compatibility with the previous namespace of (lang, id). Anywhere the previous namespace is used will log deprecation warnings.

The new behavior is the following:

When a user specifies a stored script, that script will be stored under both the new namespace and old namespace.

Take for example script 'A' with lang 'L0' and data 'D0'. If we add script 'A' to the empty set, the scripts map will be ["A" -- D0, "A#L0" -- D0]. If a script 'A' with lang 'L1' and data 'D1' is then added, the scripts map will be ["A" -- D1, "A#L1" -- D1, "A#L0" -- D0].

When a user deletes a stored script, that script will be deleted from both the new namespace (if it exists) and the old namespace.

Take for example a scripts map with {"A" -- D1, "A#L1" -- D1, "A#L0" -- D0}. If a script is removed specified by an id 'A' and lang null then the scripts map will be {"A#L0" -- D0}. To remove the final script, the deprecated namespace must be used, so an id 'A' and lang 'L0' would need to be specified.

When a user gets/executes a stored script, if the new namespace is used then the script will be retrieved/executed using only 'id', and if the old namespace is used then the script will be retrieved/executed using 'id' and 'lang'

Nik Everett 8a2d424d68 Generate reference links for painless API (#22775)
Adds "Appending B. Painless API Reference", a reference of all classes
and methods available from Painless. Removes links to java packages
because they contain methods that we don't expose and don't contain
methods that we do expose (the ones in Augmentation). Instead this
generates a list of every class and every exposed method using the same
type information available to the
interpreter/compiler/whatever-we-call-it. From there you can jump to
the relevant docs.

Right now you build all the asciidoc files by running
```
gradle generatePainlessApi
```

These files are expected to be committed because we build the docs
without running `gradle`.

Also changes the output of `Debug.explain` so that it is easy to
search for the class in the generated reference documentation.

You can also run it in an IDE safely if you pass the path to the
directory in which to generate the docs as the first parameter. It'll
blow away the entire directory an recreate it from scratch so be careful.

And then you can build the docs by running something like:
```
../docs/build_docs.pl --out ../built_docs/ --doc docs/reference/index.asciidoc --open
```

That is, if you have checked out https://github.com/elastic/docs in
`../docs`. Wait a minute or two and your browser will pop open in with
all of Elasticsearch's reference documentation. If you go to
`http://localhost:8000/painless-api-reference.html` you can see this
list. Or you can get there by following the links to `Modules` and
`Scripting` and `Painless` and then clicking the link in the paragraphs
below titled `Appendix B. Painless API Reference`.

I like having these in asciidoc because we can deep link to them from the
rest of the guide with constructs like
`<<painless-api-reference-Object-hashCode-0>>` and
`<<painless-api-reference->>` and we get link checking. Then the only
brittle link maintenance bit is the link generation for javadoc. Which
sucks. But I think it is important that we link to the methods directly
so they are easy to find.

Jason Tedor b7995fbc0d Fix default port for unicast zen ping hosts
Today when you do not specify a port for an entry in
discovery.zen.ping.unicast.hosts, the default port is the value of the
setting transport.profiles.default.port and falls back to the value of
transport.tcp.port if this is not set. For a node that is explicitly
bound to a different port than the default port, this means that the
default port will be equal to this explicitly bound port. Yet, the docs
say that we fall back to 9300 here. This commit corrects the docs.

Dave Richardson eaefb5f99b Descriptions for scripting enabled (#22388)
The `Script source settings` section currently states that `false` means scripting is ENABLED.
The other sections seem to indicate that `false` means scripting is DISABLED.

If the current documentation is correct, that would imply that `inline` and `stored` scripting are ENABLED by default, which seems to conflict with all the other sections in the document.

Nik Everett 61597f2c20 Send error_trace by default when testing (#22195)
Sends the `error_trace` parameter with all requests sent by the
yaml test framework, including the doc snippet tests. This can be
overridden by settings `error_trace: false`. While this drift's
core's handling of the yaml tests from the client's slightly this
should only be a problem for tests that rely on the default value,
both of which I've fixed by setting the value explicitly.

This also escapes `\n` and `\t` in the `Stash dump on failure` so
the `stack_trace` is more readable.

Also fixes `RestUpdateSettingsAction` to not think of the `error_trace`
parameter as a setting.

Jason Tedor b9df2e2287 Improve the out-of-the-box experience
Elasticsearch can be run in a few different ways:
 - from the command line on Linux and Windows
 - as a service on Linux and Windows

on both 32-bit client and 64-bit server VMs. We strive for a great
out-of-the-box experience any of these combinations but today it is
lacking on 32-bit client JVMs and on the Windows service. There are two
deficiencies that arise:
 - on any 32-bit client JVM we fail to start out of the box because we
   force the server JVM in jvm.options
 - when installing the Windows service, the thread stack size must be
   specified in jvm.options

This commit attempts to address these deficiencies.

We should continue to force the server JVM because there are systems
where the server JVM is not active by default (e.g., the 32-bit JDK on
Windows). This does mean that if a user tries to run with a client JVM
they will see a failure message at startup but this is the best that we
can do if we want to continue to force the server JVM. Thus, this commit
at least documents this situation.

To improve the situation with installing the Windows service, this
commit adds a default setting for the thread stack size. This default is
chosen based on the default thread stack size across all 64-bit server
JVMs. This means that if a user tries to run with a 32-bit JVM they
could otherwise see significantly higher memory usage (this situation is
complicated, it's really only on Windows where the extra memory usage is
egregious, but cutting into the 32-bit address space on any system is
bad). So this commit makes it so that the out-of-the-box experience is
improved for the Windows service on 64-bit server JVMs and we document
the need to adjust this setting on 32-bit JVMs.

Again, we are focusing on the out-of-the-box experience here and this
means optimizing for the best experience on any 64-bit server JVM as
this covers the vast majority of the user base. The users that are on
32-bit JVMs will suffer a little bit but at least now any user on any
64-bit server JVM can start Elasticsearch out of the box.

Finally, we fix some references to the jvm.options documentation.

Jason Tedor 9dc65037bc Lazy resolve unicast hosts
Today we eagerly resolve unicast hosts. This means that if DNS changes,
we will never find the host at the new address. Moreover, a single host
failng to resolve causes startup to abort. This commit introduces lazy
resolution of unicast hosts. If a DNS entry changes, there is an
opportunity for the host to be discovered. Note that under the Java
security manager, there is a default positive cache of infinity for
resolved hosts; this means that if a user does want to operate in an
environment where DNS can change, they must adjust
networkaddress.cache.ttl in their security policy. And if a host fails
to resolve, we warn log the hostname but continue pinging other
configured hosts.

When doing DNS resolutions for unicast hostnames, we wait until the DNS
lookups timeout. This appears to be forty-five seconds on modern JVMs,
and it is not configurable. If we do these serially, the cluster can be
blocked during ping for a lengthy period of time. This commit introduces
doing the DNS lookups in parallel, and adds a user-configurable timeout
for these lookups.

Nik Everett ae468441dc Implement the ?: operator in painless (#21506)
Implements a null coalescing operator in painless that looks like `?:`. This form was chosen to emulate Groovy's `?:` operator. It is different in that it only coalesces null values, instead of Groovy's `?:` operator which coalesces all falsy values. I believe that makes it the same as Kotlin's `?:` operator. In other languages this operator looks like `??` (C#) and `COALESCE` (SQL) and `:-` (bash).

This operator is lazy, meaning the right hand side is only evaluated at all if the left hand side is null.

Nik Everett d03b8e4abb Implement reading from null safe dereferences
Null safe dereferences make handling null or missing values shorter.
Compare without:
```
if (ctx._source.missing != null && ctx._source.missing.foo != null) {
  ctx._source.foo_length = ctx.source.missing.foo.length()
}
```

To with:
```
Integer length = ctx._source.missing?.foo?.length();
if (length != null) {
  ctx._source.foo_length = length
}
```

Combining this with the as of yet unimplemented elvis operator allows
for very concise defaults for nulls:
```
ctx._source.foo_length = ctx._source.missing?.foo?.length() ?: 0;
```

Since you have to start somewhere, we started with null safe dereferenes.

Anyway, this is a feature borrowed from groovy. Groovy allows writing to
null values like:
```
def v = null
v?.field = 'cat'
```
And the writes are simply ignored. Painless doesn't support this at this
point because it'd be complex to implement and maybe not all that useful.

There is no runtime cost for this feature if it is not used. When it is
used we implement it fairly efficiently, adding a jump rather than a
temporary variable.

This should also work fairly well with doc values.

Nik Everett 3a7a218e8f Support negative array ofsets in painless
Adds support for indexing into lists and arrays with negative
indexes meaning "counting from the back". So for if
`x = ["cat", "dog", "chicken"]` then `x[-1] == "chicken"`.

This adds an extra branch to every array and list access but
some performance testing makes it look like the branch predictor
successfully predicts the branch every time so there isn't a
in execution time for this feature when the index is positive.
When the index is negative performance testing showed the runtime
is the same as writing `x[x.length - 1]`, again, presumably thanks
to the branch predictor.

Those performance metrics were calculated for lists and arrays but
`def`s get roughly the same treatment though instead of inlining
the test they need to make a invoke dynamic so we don't screw up
maps.

Lee Hinman 2be52eff09 Circuit break the number of inline scripts compiled per minute
When compiling many dynamically changing scripts, parameterized
scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)
should be preferred. This enforces a limit to the number of scripts that
can be compiled within a minute. A new dynamic setting is added -
`script.max_compilations_per_minute`, which defaults to 15.

If more dynamic scripts are sent, a user will get the following
exception:

```json
{
  "error" : {
    "root_cause" : [
      {
        "type" : "circuit_breaking_exception",
        "reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",
        "bytes_wanted" : 0,
        "bytes_limit" : 0
      }
    ],
    "type" : "search_phase_execution_exception",
    "reason" : "all shards failed",
    "phase" : "query",
    "grouped" : true,

        "reason" : {

          "reason" : "Failed to compile inline script [\"aaaaaaaaaaaaaaaa\"] using lang [painless]",
          "caused_by" : {
            "type" : "circuit_breaking_exception",
            "reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",
            "bytes_wanted" : 0,
            "bytes_limit" : 0
          }
        }
      }
    ],
    "caused_by" : {
      "type" : "general_script_exception",
      "reason" : "Failed to compile inline script [\"aaaaaaaaaaaaaaaa\"] using lang [painless]",
      "caused_by" : {
        "type" : "circuit_breaking_exception",
        "reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",

        "bytes_limit" : 0
      }
    }
  },
  "status" : 500
}
```

This also fixes a bug in `ScriptService` where requests being executed
concurrently on a single node could cause a script to be compiled
multiple times (many in the case of a powerful node with many shards)
due to no synchronization between checking the cache and compiling the
script. There is now synchronization so that a script being compiled
will only be compiled once regardless of the number of concurrent
searches on a node.

Nik Everett 8d3ef742db Painless: =~ and ==~ operators
Adds support for the find operator (=~) and the match operator (==~)
to painless's regexes. Also whitelists most of the Matcher class and
documents regex support in painless.

The find operator (=~) returns a boolean that is the result of building
a matcher on the lhs with the Pattern on the RHS and calling `find` on
it. Use it like this:

```
if (ctx._source.last =~ /b/)
```

The match operator (==~) returns boolean like find but instead of calling
`find` on the Matcher it calls `matches`.

```
if (ctx._source.last ==~ /[^aeiou].*[aeiou]/)
```

Finally, if you want the actual matcher you do:

```
Matcher m = /[aeiou]/.matcher(ctx._source.last)
```

Jason Tedor da74323141 Register thread pool settings
This commit refactors the handling of thread pool settings so that the
individual settings can be registered rather than registering the top
level group. With this refactoring, individual plugins must now register
their own settings for custom thread pools that they need, but a
dedicated API is provided for this in the thread pool module. This
commit also renames the prefix on the thread pool settings from
"threadpool" to "thread_pool". This enables a hard break on the settings
so that:
 - some of the settings can be given more sensible names (e.g., the max
   number of threads in a scaling thread pool is now named "max" instead
   of "size")
 - change the soft limit on the number of threads in the bulk and
   indexing thread pools to a hard limit
 - the settings names for custom plugins for thread pools can be
   prefixed (e.g., "xpack.watcher.thread_pool.size")
 - remove dynamic thread pool settings

This removes all the mentions of the sandbox from the script engine
services and permissions model. This means that the following settings
are no longer supported:

```yaml
script.inline: sandbox
script.stored: sandbox
```

Instead, only a `true` or `false` value can be specified.

Since this would otherwise break the default-allow parameter for
languages like expressions, painless, and mustache, all script engines
have been updated to have individual settings, for instance:

```yaml
script.engine.groovy.inline: true
```

Would enable all inline scripts for groovy. (they can still be
overridden on a per-operation basis).

Expressions, Painless, and Mustache all default to `true` for inline,
file, and stored scripts to preserve the old scripting behavior.

For example, accessing fields can now be done with `.value` instead of `.0`
because `getValue()` is whitelisted. For now, access to a document's fields in
this way (loads) are fast-pathed in the code, to avoid dynamic overhead.

Access to geo fields and geo distance functions is now supported.

Adds infrastructure so `gradle :docs:check` will extract tests from
snippets in the documentation and execute the tests. This is included
in `gradle check` so it should happen on CI and during a normal build.

By default each `// AUTOSENSE` snippet creates a unique REST test. These
tests are executed in a random order and the cluster is wiped between
each one. If multiple snippets chain together into a test you can annotate
all snippets after the first with `// TEST[continued]` to have the
generated tests for both snippets joined.

Snippets marked as `// TESTRESPONSE` are checked against the response
of the last action.

constructed with a core pool size of four, a max pool size of 128 and
idle workers can be reaped after a keep-alive time of thirty seconds
expires. The work queue for this thread pool remains unbounded.

Daniel Mitterdorfer 52b2016447 Limit request size on transport level
With this commit we limit the size of all in-flight requests on
transport level. The size is guarded by a circuit breaker and is
based on the content size of each request.

By default we use 100% of available heap meaning that the parent
circuit breaker will limit the maximum available size. This value
can be changed by adjusting the setting

network.breaker.inflight_requests.limit

We currently have a `discovery.zen.master_election.filter_client` setting that control whether their ping responses are ignored for master election (which is the current default). With the push to treat client nodes as normal nodes (and promote the transport/rest clients for client work), this should be changed. This commit remove this setting and it's companion `discovery.zen.master_election.filter_data` setting (currently defaulting to  false) in favor of singe `discovery.zen.master_election.ignore_non_master_pings` setting with more intuitive name (defaulting to false).

Jason Tedor 8a05c2a2be Bootstrap does not set system properties
Today, certain bootstrap properties are set and read via system
properties. This action-at-distance way of managing these properties is
rather confusing, and completely unnecessary. But another problem exists
with setting these as system properties. Namely, these system properties
are interpreted as Elasticsearch settings, not all of which are
registered. This leads to Elasticsearch failing to startup if any of
these special properties are set. Instead, these properties should be
kept as local as possible, and passed around as method parameters where
needed. This eliminates the action-at-distance way of handling these
properties, and eliminates the need to register these non-setting
properties. This commit does exactly that.

Additionally, today we use the "-D" command line flag to set the
properties, but this is confusing because "-D" is a special flag to the
JVM for setting system properties. This creates confusion because some
"-D" properties should be passed via arguments to the JVM (so via
ES_JAVA_OPTS), and some should be passed as arguments to
Elasticsearch. This commit changes the "-D" flag for Elasticsearch
settings to "-E".

David Pilato 26863a4d75 Fix: Change docs on "node client" to not use an in-memory node
Currently we suggesting users create a Node (using NodeBuilder in 2.x) to have a client that is capable of keeping up-to-date information. This is generally a bad idea as it means elasticsearch has no control over eg max heap size or gc settings, and is also problematic for users because they must deal with dependency collisions (and in 2.x+ dependencies of elasticsearch itself).

A better alternative, and what we should document, is to run a local elasticsearch server using bin/elasticsearch, and then use the transport client to connect to that local node. This local connection is virtually free, and allows the client code to be completely isolated from the elasticsearch process. Plugins are then also easy to deal with: just install them in elasticsearch as usual.

Simon Willnauer f5e4cd4616 Remove recovery threadpools and throttle outgoing recoveries on the master
Today we throttle recoveries only for incoming recoveries. Nodes that have a lot
of primaries can get overloaded due to too many recoveries. To still keep that at bay
we limit the number of threads that are sending files to the target to overcome this problem.

The right solution here is to also throttle the outgoing recoveries that are today unbounded on
the master and don't start the recovery until we have enough resources on both source and target nodes.

The concurrency aspects of the recovery source also added a lot of complexity and additional threadpools
that are hard to configure. This commit removes the concurrent streamns notion completely and sends files
in the thread that drives the recovery simplifying the recovery code considerably.
Outgoing recoveries are not throttled on the master via a allocation decider.

Robert Muir 7595c4a3c8 Improve network docs
This makes some minor improvements (does not fix all problems!)

It reorders unicast disco in elasticsearch.yml to be right after the network host,
for better locality.

It removes the warning (unreleased) about publish addresses, lets try to really discourage setting
that unless you need to (behind a proxy server). Most people should be fine with `network.host`

Finally it reorganizes the network docs page a bit:

We add a table of 4 "basic" settings at the very beginning:

* network.host
* discovery.zen.ping.unicast.hosts
* http.port
* transport.tcp.port

The first two being the most important, which addresses to bind and talk to, and the other two
being the port numbers.

The rest of the stuff I tried to simplify and reorder under "advanced" headers.

This is just a quick stab, I still think we need more effort into this thing, but we gotta start somewhere.

Which gives back the private IP address, for example `10.240.0.2`.

http://metadata.google.internal/computeMetadata/v1/instance/network-interfaces/0/externalIp

Gives back the public Ip address, for example `130.211.108.21`.

As we have for `ec2`, we can support new network host settings:

* `_gce:privateIp:X_`: The private IP address of the machine for a given network interface.
* `_gce:hostname_`: The hostname of the machine.
* `_gce_`: Same as `_gce:privateIp:0_` (recommended).

    Handle node mode across entire test cluster

    We used static methods reading sys properties to define the node mode
    per cluster. this had lots of problems when tests couldn't cope with
    mixed or only local mode. Now we are passing it down to the cluster from the test
    which allows to @SuppressNetworkMode / @SupressLocalMode on the test to force
    consistent node configurations.

Robert Muir 68307aa9f3 Fix network binding for ipv4/ipv6
When elasticsearch is configured by interface (or default: loopback interfaces),
bind to all addresses on the interface rather than an arbitrary one.

If the publish address is not specified, default it from the bound addresses
based on the following sort ordering:

* ipv4/ipv6 (java.net.preferIPv4Stack, defaults to true)
* ordinary addresses
* site-local addresses
* link local addresses
* loopback addresses

One one address is published, and multicast is still always over ipv4: these
need to be future improvements.

Today this is "unofficial" as conf/scripts, but some people
want to share scripts across different nodes and so on. Because
they cannot configure it, they are forced to use dirty hacks
like symbolic links, which isnt going to work: we aren't going
to recursively scan conf/ and add permissions to all link targets
underneath it, thats crazy.

I really hate adding yet another configuration knob here, but
users resorting to using symlinks are going to be frustrated,
and do things in a more insecure way.

Boaz Leskes 1e35bf3171 Discovery: wait on incoming joins before electing local node as master
During master election each node pings in order to discover other nodes and validate the liveness of existing nodes. Based on this information the node either discovers an existing master or, if enough nodes are found (based on `discovery.zen.minimum_master_nodes>>) a new master will be elected.

Currently, the node that is elected as master will currently update it the cluster state to indicate the result of the election. Other nodes will submit a join request to the newly elected master node. Instead of immediately processing the election result, the elected master
node should wait for the incoming joins from other nodes, thus validating the elections result is properly applied. As soon as enough nodes have sent their joins request (based on the `minimum_master_nodes` settings) the cluster state is modified.

Note that if `minimum_master_nodes` is not set, this change has no effect.

David Pilato d57de59158 Simplify Plugin Manager for official plugins
Plugin Manager can now use another simplified form when a user wants to install an official plugin hosted at elasticsearch download service.

The form we use is:

```sh
bin/plugin install pluginname
```

As plugins share now the same version as elasticsearch, we can automatically guess what is the exact current version of the plugin manager script.

Also, download service will now use `/org.elasticsearch.plugins/pluginName/pluginName-version.zip` URL path to download a plugin.

If the older form is provided (`user/plugin/version` or `user/plugin`), we will still use:

 * elasticsearch download service at `/user/plugin/plugin-version.zip`
 * maven central with groupIp=user, artifactId=plugin and version=version
 * github with user=user, repoName=plugin and tag=version
 * github with user=user, repoName=plugin and branch=master if no version is set

Note that community plugin providers can use other download services by using `--url` option.

If you try to use the new form with a non core elasticsearch plugin, the plugin manager will reject
it and will give you all known core plugins.

```
Usage:
    -u, --url     [plugin location]   : Set exact URL to download the plugin from
    -i, --install [plugin name]       : Downloads and installs listed plugins [*]
    -t, --timeout [duration]          : Timeout setting: 30s, 1m, 1h... (infinite by default)
    -r, --remove  [plugin name]       : Removes listed plugins
    -l, --list                        : List installed plugins
    -v, --verbose                     : Prints verbose messages
    -s, --silent                      : Run in silent mode
    -h, --help                        : Prints this help message

 [*] Plugin name could be:
     elasticsearch-plugin-name    for Elasticsearch 2.0 Core plugin (download from download.elastic.co)
     elasticsearch/plugin/version for elasticsearch commercial plugins (download from download.elastic.co)

Adrien Grand 38f5cc236a Rename caches.
In order to be more consistent with what they do, the query cache has been
renamed to request cache and the filter cache has been renamed to query
cache.

A known issue is that package/logger names do no longer match settings names,
please speak up if you think this is an issue.

Here are the settings for which I kept backward compatibility. Note that they
are a bit different from what was discussed on #11569 but putting `cache` before
the name of what is cached has the benefit of making these settings consistent
with the fielddata cache whose size is configured by
`indices.fielddata.cache.size`:
 * index.cache.query.enable -> index.requests.cache.enable
 * indices.cache.query.size -> indices.requests.cache.size
 * indices.cache.filter.size -> indices.queries.cache.size

jaymode 6b086dc7db change CORS allow origin default to allow no origins
Today, we disable CORS by default, but if a user simply enables CORS their instance of
elasticsearch will allow cross origin requests from anywhere, as the default value for allowed
origins is `*`.

This changes the default to be `null` so that no origins are allowed and the user must explicitly
specify the origins they wish to allow requests from. The documentation also mentions that there
is a security risk in using `*` as the value.

Information about in-progress snapshot and restore processes is not really metadata and should be represented as a part of the cluster state similar to discovery nodes, routing table, and cluster blocks. Since in-progress snapshot and restore information is no longer part of metadata, this refactoring also enables us to handle cluster blocks in more consistent manner and allow creation of snapshots of a read-only cluster.

Adrien Grand ac7ce2b899 Rivers removal.
While we had initially planned to keep rivers around in 2.0 to ease migration,
keeping support for rivers is challenging as it conflicts with other important
changes that we want to bring to 2.0 like synchronous dynamic mappings updates.
Nothing impossible to fix, but it would increase the complexity of how we
deal with dynamic mappings updates and manage rivers, while handling dynamic
mappings updates correctly is important for resiliency and rivers are on the go.
So removing rivers in 2.0 may well be a better trade-off.

javanna c914134355 Scripting: remove groovy sandbox

Clinton Gormley 37ed61807f Docs: Updated the experimental annotations in the docs as follows:
* Removed the docs for `index.compound_format` and `index.compound_on_flush` - these are expert settings which should probably be removed (see https://github.com/elastic/elasticsearch/issues/10778)
* Removed the docs for `index.index_concurrency` - another expert setting
* Labelled the segments verbose output as experimental
* Marked the `compression`, `precision_threshold` and `rehash` options as experimental in the cardinality and percentile aggs
* Improved the experimental text on `significant_terms`, `execution_hint` in the terms agg, and `terminate_after` param on count and search
* Removed the experimental flag on the `geobounds` agg
* Marked the settings in the `merge` and `store` modules as experimental, rather than the modules themselves

javanna 7bd7ea8f13 Scripting: allow plugins to define custom operations that they use scripts for
Plugins can now define multiple operations/contexts that they use scripts for. Fine-grained settings can then be used to enable/disable scripts based on each single registered context.

Also added a new generic category called `plugin`, which will be used as a default when the context is not specified. This allows us to restore backwards compatibility for plugins on `ScriptService` by restoring the old methods that don't require the script context and making them internally use the `plugin` context, as they can only be called from plugins.

javanna 83fb0a10e5 Scripting: remove support for script.disable_dynamic setting
Now that fine-grained script settings are supported (#10116) we can remove support for the script.disable_dynamic setting.

Same result as `script.disable_dynamic: false` can be obtained as follows:

```
script.inline: on
script.indexed: on
```
An exception is thrown at startup when the old setting is set, so we make sure we tell users they have to change it rather than ignoring the setting.

javanna d9d1e6a67a Scripting: add support for fine-grained settings
Allow to on/off scripting based on their source (where they get loaded from), the  operation that executes them and their language.

The settings cover the following combinations:

- mode: on, off, sandbox
- source: indexed, dynamic, file
- engine: groovy, expressions, mustache, etc
- operation: update, search, aggs, mapping

The following settings are supported for every engine:

script.engine.groovy.indexed.update:    sandbox/on/off
script.engine.groovy.indexed.search:    sandbox/on/off
script.engine.groovy.indexed.aggs:      sandbox/on/off
script.engine.groovy.indexed.mapping:   sandbox/on/off
script.engine.groovy.dynamic.update:    sandbox/on/off
script.engine.groovy.dynamic.search:    sandbox/on/off
script.engine.groovy.dynamic.aggs:      sandbox/on/off
script.engine.groovy.dynamic.mapping:   sandbox/on/off
script.engine.groovy.file.update:       sandbox/on/off
script.engine.groovy.file.search:       sandbox/on/off
script.engine.groovy.file.aggs:         sandbox/on/off
script.engine.groovy.file.mapping:      sandbox/on/off

For ease of use, the following more generic settings are supported too:

script.indexed: sandbox/on/off
script.dynamic: sandbox/on/off
script.file:    sandbox/on/off

script.update:  sandbox/on/off
script.search:  sandbox/on/off
script.aggs:    sandbox/on/off
script.mapping: sandbox/on/off

These will be used to calculate the more specific settings, using the stricter setting of each combination. Operation based settings have precedence over conflicting source based ones.

Note that the `mustache` engine is affected by generic settings applied to any language, while native scripts aren't as they are static by definition.

Also, the previous `script.disable_dynamic` setting can now be deprecated.
