Added minimal docs for reindex api in java-api docs
Additionally:
* Included the existing update by query java api docs in java-api docs.
  (for some reason it was never included, it needed some tweaking and
  then it was good to go)
* moved delete-by-query / update-by-query code samples to java file so
  that we can verify that these samples at least compile.

Closes #24203

Decouple XContentBuilder from BytesReference (#28972)
* Decouple XContentBuilder from BytesReference

This commit removes all mentions of `BytesReference` from `XContentBuilder`.
This is needed so that we can completely decouple the XContent code and move it
into its own dependency.

While this change appears large, it is due to two main changes, moving
`.bytes()` and `.string()` out of XContentBuilder itself into static methods
`BytesReference.bytes` and `Strings.toString` respectively. The rest of the
change is code reacting to these changes (the majority of it in tests).

Wrap stream passed to createParser in try-with-resources (#28897)
* Wrap stream passed to createParser in try-with-resources

This wraps the stream (`.streamInput()`) that is passed to many of the
`createParser` instances in the enclosing (or a new) try-with-resources block.
This ensures the `BytesReference.streamInput()` is closed.

Pass InputStream when creating XContent parser (#28754)
* Pass InputStream when creating XContent parser

Rather than passing the raw `BytesReference` in when creating the xcontent
parser, this passes the StreamInput (which is an InputStream), this allows us to
decouple XContent from BytesReference.

This also removes the use of `commons.Booleans` so it doesn't require more
external commons classes.

Nik Everett 9aeed74fe9 Reindex: Raise timeout on flaky test
This gives the test longer to block its updates. Now that we're checking
if the updates actually blocked saw that they may not do so in the

Nik Everett 2eede9b876 Reindex: Shore up rethrottle test
The rethrottle test fails from time to time because one of the child
task that want to be rethrottled hasn't properly started yet. We retry
in this case but it looks like the retry either isn't long enough or
something else strange is happening.

This change adds yet more logging so future failure of this kind will be
easier to track down and it adds an extra wait condition: this waits for
all child tasks to be running or completed before rethrottling. This
*might* avoid the failure because once a child task is properly started
it should be quite ok to rethrottle.

Nik Everett eded5bc4f3 Reindex: Wait for deletion in test
The test failure tracked by #28053 occurs because we fail to get the
failure response from the reindex on the first try and on our second try
the delete index API call that was supposed to trigger the failure
actually deletes the index during document creation. This causes the
test to fail catastrophically.

This PR attempts to wait for the failure to finish before the test moves
on to the second attempt. The failure doesn't reproduce locally for me
so I can't be sure that this helps at all with the failure, but it
certainly feels like it should help some. Here is hoping this prevents
similar failures in the future.

Nik Everett 049f29710e Reindex: log more on rare test failure
The test failure tracked by #26758 occurs when we cancel a running reindex
request that has been sliced into many children. The main reindex
response *looks* canceled but none of the children look canceled. This
is super strange because for the main request to look canceled for any
length of time one of the children has to be canceled.

This change adds additional logging to the test so we have more to go on
to debug this the next time it fails.

Cross Cluster Search: make remote clusters optional (#27182)
Today Cross Cluster Search requires at least one node in each remote cluster to be up once the cross cluster search is run. Otherwise the whole search request fails despite some of the data (either local and/or remote) is available. This happens when performing the _search/shards calls to find out which remote shards the query has to be executed on. This scenario is different from shard failures that may happen later on when the query is actually executed, in case e.g. remote shards are missing, which is not going to fail the whole request but rather yield partial results, and the _shards section in the response will indicate that.

This commit introduces a boolean setting per cluster called search.remote.$cluster_alias.skip_if_disconnected, set to false by default, which allows to skip certain clusters if they are down when trying to reach them through a cross cluster search requests. By default all clusters are mandatory.

Scroll requests support such setting too when they are first initiated (first search request with scroll parameter), but subsequent scroll rounds (_search/scroll endpoint) will fail if some of the remote clusters went down meanwhile.

The search API response contains now a new _clusters section, similar to the _shards section, that gets returned whenever one or more clusters were disconnected and got skipped:

"_clusters" : {
    "total" : 3,
    "successful" : 2,
    "skipped" : 1
}
Such section won't be part of the response if no clusters have been skipped.

The per cluster skip_unavailable setting value has also been added to the output of the remote/info API.

Plugins: Add versionless alias to all security policy codebase properties (#26756)
This is a followup to #26521. This commit expands the alias added for
the elasticsearch client codebase to all codebases. The original full
jar name property is left intact. This only adds an alias without the
version, which should help ease the pain in updating any versions (ES
itself or dependencies).

Jason Tedor 9aae2f593a Avoid stack overflow on search phases
When a search is executing locally over many shards, we can stack
overflow during query phase execution. This happens due to callbacks
that occur after a phase completes for a shard and we move to the same
phase on another shard. If all the shards for the query are local to the
local node then we will never go async and these callbacks will end up
as recursive calls. With sufficiently many shards, this will end up as a
stack overflow. This commit addresses this by truncating the stack by
forking to another thread on the executor for the phase.

Ryan Ernst c9964d17bf Internal: Add versionless alias for rest client codebase in policy files (#26521)
Security manager policy files contains grants for specific codebases,
where a codebase is a jar file. We use a system property containing the
name of the jar file to resolve the jar file location when parsing the
policy file. However, this means the version of the jars must be
modified when versions of dependencies change. This is particularly
messy for elasticsearch, where we now have a dependency on the rest
client, and need to support both a snapshot version for testing and non
snapshot for release.

This commit adds an alias for the elasticsearch rest client without a
version to be used in policy files. That allows the policy files to not care whether
the rest client is a snapshot or release.

Andy Bristol 7e3cd6a019 reindex: automatically choose the number of slices (#26030)
In reindex APIs, when using the `slices` parameter to choose the number of slices, adds the option to specify `slices` as "auto" which will choose a reasonable number of slices. It uses the number of shards in the source index, up to a ceiling. If there is more than one source index, it uses the smallest number of shards among them.

This gives users an easy way to use slicing in these APIs without having to make decisions about how to configure it, as it provides a good-enough configuration for them out of the box. This may become the default behavior for these APIs in the future.

Simon Willnauer e81804cfa4 Add a shard filter search phase to pre-filter shards based on query rewriting (#25658)
Today if we search across a large amount of shards we hit every shard. Yet, it's quite
common to search across an index pattern for time based indices but filtering will exclude
all results outside a certain time range ie. `now-3d`. While the search can potentially hit
hundreds of shards the majority of the shards might yield 0 results since there is not document
that is within this date range. Kibana for instance does this regularly but used `_field_stats`
to optimize the indexes they need to query. Now with the deprecation of `_field_stats` and it's upcoming removal a single dashboard in kibana can potentially turn into searches hitting hundreds or thousands of shards and that can easily cause search rejections even though the most of the requests are very likely super cheap and only need a query rewriting to early terminate with 0 results.

This change adds a pre-filter phase for searches that can, if the number of shards are higher than a the `pre_filter_shard_size` threshold (defaults to 128 shards), fan out to the shards
and check if the query can potentially match any documents at all. While false positives are possible, a negative response means that no matches are possible. These requests are not subject to rejection and can greatly reduce the number of shards a request needs to hit. The approach here is preferable to the kibana approach with field stats since it correctly handles aliases and uses the correct threadpools to execute these requests. Further it's completely transparent to the user and improves scalability of elasticsearch in general on large clusters.

setup documents of multiple types. This whole feature can be dropped

Nik Everett 3261586cac Tweak reindex cancel logic and add many debug logs (#25256)
I'm still trying to hunt down rare failures in the cancelation tests
for reindex and friends. Here is the latest:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+5.x+multijob-unix-compatibility/os=ubuntu/876/console

It doesn't show much, other than that one of the tasks didn't kill
itself when asked to cancel.

So I'm going a bit crazy with debug logging so that the next time this
comes up I can trace exactly what happened.

Additionally, this tweaks the logic around how rethrottles were
performed around cancel. Previously we set the `requestsPerSecond`
to `0` when we cancelled the task. That was the "old way" to set them
to inifity which was the intent. This switches that from `0` to

Chris Earle 6464add551 Always Accumulate Transport Exceptions (#25017)
This removes the `accumulateExceptions()` method (and its usage) from `TransportNodesAction` and `TransportTasksAction`, forcing both transport actions to always accumulate exceptions.

Without this change, some transport actions, like `TransportNodesStatsAction` would respond in very unexpected ways by returning no response due to some failure, but instead of returning an
error the response would simply be empty: no response and no error.

This results in a very trappy response structure where users can check for an error, then attempt to blindly use the response when no error is returned.

Colin Goodheart-Smithe 779fb9a1c0 Adds nodes usage API to monitor usages of actions (#24169)
* Adds nodes usage API to monitor usages of actions

The nodes usage API has 2 main endpoints

/_nodes/usage and /_nodes/{nodeIds}/usage return the usage statistics
for all nodes and the specified node(s) respectively.

At the moment only one type of usage statistics is available, the REST
actions usage. This records the number of times each REST action class is
called and when the nodes usage api is called will return a map of rest
action class name to long representing the number of times each of the action
classes has been called.

Still to do:

* [x] Create usage service to store usage statistics
* [x] Record usage in REST layer
* [x] Add Transport Actions
* [x] Add REST Actions
* [x] Tests
* [x] Documentation

* Rafactors UsageService so counts are done by the handlers

* Fixing up docs tests

* Adds a name to all rest actions

* Addresses review comments

This is a simple refactoring to move the context definitions into the

instance type, so the pattern of a static member on the interface called
CONTEXT can be used. This commit also moves the consolidated list of
contexts provided by core ES into ScriptModule.

Ryan Ernst 1daacd97b0 Scripting: Add instance and compiled classes to script contexts (#24868)
This commit modifies the compile method of ScriptService to be context
aware. The ScriptContext is now a generic class which contains both the
instance type and compiled type for a script. Instance type may be
stateful (for example, pre loading field information for the index a
script will execute on, like in expressions), while the compiled type is
stateless and used to construct instance type instances. This change is
only a first step to cutover ScriptService to the new paradigm. It only
converts callers to the script service, and has a small shim to wrap
compilation from the script engines to support the current two fixed
instance types, SearchScript and ExecutableScript.

Today when an index is `read-only` the index is also blocked from

it clear that the tests don't need the default scripting language.

rejected these requets as accepting them could be a dangerous form of

not need a second way. This commit rejects the individual requests where

Ryan Ernst 175bda64a0 Build: Rework integ test setup and shutdown to ensure stop runs when desired (#23304)
Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).

This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`.  The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.

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.
