David Pilato af989c0780 Support new Asia Pacific (Mumbai) ap-south-1 AWS region
AWS [announced](http://www.allthingsdistributed.com/2016/06/introducing-aws-asia-pacific-mumbai-region.html) a new region: Asia Pacific (Mumbai)	`ap-south-1`.

We need to support it for:

* repository-s3: s3.ap-south-1.amazonaws.com or s3-ap-south-1.amazonaws.com
* discovery-ec2: ec2.ap-south-1.amazonaws.com

For reference: http://docs.aws.amazon.com/general/latest/gr/rande.html

Closes #19110.

Jason Tedor 2f638b5a23 Keep input time unit when parsing TimeValues
This commit modifies TimeValue parsing to keep the input time unit. This
enables round-trip parsing from instances of String to instances of
TimeValue and vice-versa. With this, this commit removes support for the
unit "w" representing weeks, and also removes support for fractional
values of units (e.g., 0.5s).

Martijn van Groningen d3cd58eb2f Merges PR #18957
This commit fixes several NPEs caused by implicitly performing a get request for a document that exists with its _source disabled and then trying to access the source. Instead of causing an NPE the following queries will throw an exception with a "source disabled" message (similar behavior as if the document does not exist).:
- GeoShape query for pre-indexed shape (throws IllegalArgumentException)
- Percolate query for an existing document (throws IllegalArgumentException)

A Terms query with a lookup will ignore the document if the source does not exist (same as if the document does not exist).

GET and HEAD requests for the document _source will return a 404 if the source is disabled (even if the document exists).

Nik Everett 71b95fb63c Switch analysis from push to pull
Instead of plugins calling `registerTokenizer` to extend the analyzer
they now instead have to implement `AnalysisPlugin` and override
`getTokenizer`. This lines up extending plugins in with extending
scripts. This allows `AnalysisModule` to construct the `AnalysisRegistry`
immediately as part of its constructor which makes testing anslysis
much simpler.

This also moves the default analysis configuration into `AnalysisModule`
which is how search is setup.

Like `ScriptModule`, `AnalysisModule` no longer extends `AbstractModule`.
Instead it is only responsible for building `AnslysisRegistry`. We still
bind `AnalysisRegistry` but we only do so in `Node`. This is means it
is available at module construction time so we slowly remove the need to
bind it in guice.

Tanguy Leroux 04da1bda0d Move templates out of the Search API, into lang-mustache module
This commit moves template support out of the Search API to its own dedicated Search Template API in the lang-mustache module. It provides a new SearchTemplateAction that can be used to render templates before it gets delegated to the usual Search API. The current REST endpoint are identical, but the Render Search Template endpoint now uses the same Search Template API with a new "simulate" option. When this option is enabled, the Search Template API only renders template and returns immediatly, without executing the search.

`fields` will throw an exception if the user uses it.
Add `docvalue_fields` as an adjunct to `fielddata_fields` which is deprecated. `docvalue_fields` will try to load the value from the docvalue and fallback to fielddata cache if docvalues are not enabled on that field.

```json

Nik Everett b665d8a187 Painless: Add flag support to regexes
Painless: Add support for //m
Painless: Add support for //s
Painless: Add support for //i
Painless: Add support for //u
Painless: Add support for //U
Painless: Add support for //l
  This means "literal" and is exposed for completeness sake with
  the java api.
Painless: Add support for //c
  c enables Java's CANON_EQ (canonical equivalence) flag which makes
  unicode characters that are canonically equal match. Java's javadoc
  gives "a\u030A" being equal to "\u00E5". That is that the "a" code
  point followed by the "combining ring above" code point is equal to
  the "a with combining ring above" code point.

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)
```

Nik Everett e392e0b1df Create get task API that falls back to the .tasks index
This adds a get task API that supports GET /_tasks/${taskId} and
removes that responsibility from the list tasks API. The get task
API supports wait_for_complation just as the list tasks API does
but doesn't support any of the list task API's filters. In exchange,
it supports falling back to the .results index when the task isn't
running any more. Like any good GET API it 404s when it doesn't
find the task.

Then we change reindex, update-by-query, and delete-by-query to
persist the task result when wait_for_completion=false. The leads
to the neat behavior that, once you start a reindex with
wait_for_completion=false, you can fetch the result of the task by
using the get task API and see the result when it has finished.

Also rename the .results index to .tasks.

Martijn van Groningen 3b96055b23 msearch: Cap the number of searches the msearch api will concurrently execute
By default the number of searches msearch executes is capped by the number of
nodes multiplied with the default size of the search threadpool. This default can be
overwritten by using the newly added `max_concurrent_searches` parameter.

Before the msearch api would concurrently execute all searches concurrently. If many large
msearch requests would be executed this could lead to some searches being rejected
while other searches in the msearch request would succeed.

The goal of this change is to avoid this exhausting of the search TP.

Lee Hinman feb244c14a Remove cluster name from data path
Previously Elasticsearch used $DATA_DIR/$CLUSTER_NAME/nodes for the path
where data is stored, this commit changes that to be $DATA_DIR/nodes.

On startup, if the old folder structure is detected it will be used.
This behavior will be removed in Elasticsearch 6.0

Jim Ferenczi b9030bf6fe Add the ability to partition a scroll in multiple slices.
API:

```
curl -XGET 'localhost:9200/twitter/tweet/_search?scroll=1m' -d '{
    "slice": {
        "field": "_uid", <1>
        "id": 0, <2>
        "max": 10 <3>
    },
    "query": {
        "match" : {
            "title" : "elasticsearch"
        }
    }
}
```

<1> (optional) The field name used to do the slicing (_uid by default)
<2> The id of the slice

By default the splitting is done on the shards first and then locally on each shard using the _uid field
with the following formula:
`slice(doc) = floorMod(hashCode(doc._uid), max)`
For instance if the number of shards is equal to 2 and the user requested 4 slices then the slices 0 and 2 are assigned
to the first shard and the slices 1 and 3 are assigned to the second shard.

Each scroll is independent and can be processed in parallel like any scroll request.

Bootstrap check for OnOutOfMemoryError and seccomp

Simon Willnauer b2c4c323e1 Allow `_shrink` to N shards if source shards is a multiple of N (#18699)
Today we allow to shrink to 1 shard but that might not be possible due to
too many document or a single shard doesn't meet the requirements for the index.
The logic can be expanded to N shards if the source index shards is a multiple of N.
This guarantees that there are not hotspots created due to different number of shards
being shrunk into one.

Jason Tedor e94408c0d2 Bootstrap check for OnError and seccomp
This commit adds a bootstrap check for the JVM option OnError being in
use and seccomp being enabled. These two options are incompatible
because OnError allows the user to specify an arbitrary program to fork
when the JVM encounters an fatal error, and seccomp enables system call
filters that prevents forking.

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

Jason Tedor 9695caa3fb Bootstrap check for OnOutOfMemoryError and seccomp
This commit adds a bootstrap check for the JVM option OnOutOfMemoryError
being in use and seccomp being enabled. These two options are
incompatible because OnOutOfMemoryError allows the user to specify an
arbitrary program to fork when the JVM encounters an
OutOfMemoryError, and seccomp enables system call filters that prevents
forking.

This commit also adds support for bootstrap checks that are always
enforced, whether or not Elasticsearch is in production mode.

Nik Everett d8056c8213 Add support for waiting until a refresh occurs
This adds support for setting the refresh request parameter to
`wait_for` in the `index`, `delete`, `update`, and `bulk` APIs. When
`refresh=wait_for` is set those APIs will not return until their
results have been made visible to search by a refresh.

Also it adds a `forced_refresh` field to the response of `index`,
`delete`, `update`, and to each item in a bulk response. This will
be true for requests with `?refresh` or `?refresh=true` and will be
true for some requests (see below) with `refresh=wait_for` but ought
to otherwise always be false.

`refresh=wait_for` is implemented as a list of
`Tuple<Translog.Location, Consumer<Boolean>>`s in the new `RefreshListeners`
class that is managed by `IndexShard`. The dynamic, index scoped
`index.max_refresh_listeners` setting controls a maximum number of
listeners allowed in any shard. If more than that many listeners
accumulate in the engine then a refresh will be forced, the thread that
adds the listener will be blocked until the refresh completes, and then the
listener will be called with a `forcedRefresh` flag so it knows that it was
the "straw that broke the camel's back". These listeners are only used by
`refresh=wait_for` and that flag manifests itself as `forced_refresh` being
`true` in the response.

About half of this change comes from piping async-ness down to the appropriate
layer in a way that is compatible with the ongoing with with sequence ids.

Closes #1063

    Handle hanging documents

    If a document is added to the index during a refresh we weren't properly
    firing its refresh listener. This happened because the way we detect
    whether a refresh makes something visible or not is imperfect. It is
    ok because it always errs on the side of thinking that something isn't
    yet visible.

    So when a document arrives during a refresh the refresh listeners
    won't think it made it into a refresh when, often, it does. The way
    we work around this is by telling Elasticsearch that it ought to
    trigger a refresh if there are any pending refresh listeners even
    if there aren't pending documents to update. Lucene short circuits
    the refresh so it doesn't take that much effort, but the refresh
    listeners still get the signal that a refresh has come in and they
    still pick up the change and notify the listener.

    This means that the time that a listener can wait is actually slightly
    longer than the refresh interval.

    Remove Translog#lastWriteLocation

    I wasn't being careful enough with locks so it wasn't right anyway.
    Instead this builds a synthetic Tranlog.Location when you call
    getWriteLocation with much more relaxed equality guarantees. Rather
    than being equal to the last Translog.Location returned it is
    simply guaranteed to be greater than the last translog returned
    and less than the next.

    Move refresh listeners into their own class

    They still live at the IndexShard level but they live on their
    own in RefreshListeners which interacts with IndexShard using a
    couple of callbacks and a registration method. This lets us test
    the listeners without standing up an entire IndexShard. We still
    test the listeners against an InternalEngine, because the interplay
    between InternalEngine, Translog, and RefreshListeners is complex
    and important to get right.

    Switch to estimated count

    We don't need a linear time count of the number of listeners - a volatile
    variable is good enough to guess. It probably undercounts more than it
    overcounts but it isn't a huge problem.

    Don't try and set forced refresh on bulk items without a response

    NullPointerExceptions are bad. If the entire request fails then the user
    has worse problems then "did these force a refresh".

    Never reply to replica actions while you have the operation lock

    This last thing was causing periodic test failures because we were
    replying while we had the operation lock. Now, we probably could get
    away with that in most cases but the tests don't like it and it isn't
    a good idea to do network io while you have a lock anyway. So this
    prevents it.

    Create TransportReplicatedMutationAction

    It is the superclass of replication actions that mutate data: index, delete,
    and shardBulk. shardFlush and shardRefresh are replication actions but they
    do not extend TransportReplicatedMutationAction because they don't change
    the data, only shuffle it around.

Simon Willnauer 22dfc41521 Only filter intial recovery (post API) when shrinking an index (#18661)
Today we use `index.routing.allocation.include._id` to filter the allocation
for the shrink target index. That has the sideeffect that the user has to
delete that setting / change it once the primary has been recovered (shrink is done)
This PR adds a dedicated filter that can only be set internally that only filters
allocation for unassigned shards.

Simon Willnauer 502a775a7c Add primitive to shrink an index into a single shard (#18270)
This adds a low level primitive operations to shrink an existing
index into a new index with a single shard. This primitive expects
all shards of the source index to allocated on a single node. Once the target index is initializing on the shrink node it takes a snapshot of the source index shards and copies all files into the target indices data folder. An [optimization](https://issues.apache.org/jira/browse/LUCENE-7300) coming in Lucene 6.1 will also allow for optional constant time copy if hard-links are supported by the filesystem. All mappings are merged into the new indexes metadata once the snapshots have been taken on the merge node.

To shrink an existing index all shards must be moved to a single node (one instance of each shard) and the index must be read-only:

```BASH
$ curl -XPUT 'http://localhost:9200/logs/_settings' -d '{
    "settings" : {
        "index.routing.allocation.require._name" : "shrink_node_name",
        "index.blocks.write" : true 
    }
}
```
once all shards are started on the shrink node. the new index can be created via:

```BASH
$ curl -XPUT 'http://localhost:9200/logs/_shrink/logs_single_shard' -d '{
    "settings" : {
        "index.codec" : "best_compression",
        "index.number_of_replicas" : 1
    }
}'
```

This API will perform all needed check before the new index is created and selects the shrink node based on the allocation of the source index. This call returns immediately, to monitor shrink progress the recovery API should be used since all copy operations are reflected in the recovery API with byte copy progress etc.

The shrink operation does not modify the source index, if a shrink operation should
be canceled or if the shrink failed, the target index can simply be deleted and
all resources are released.

Martijn van Groningen 27cc2fe4dc Moved the percolator from core to its own module
Significant changes:
* AbstractQueryTestCase has moved to the test framework module, in order for query builder tests in modules and plugins
* Added support to AbstractQueryTestCase to register plugins
* Lift the restriction that only one percolator could be added per index. This validation existed in MapperService, but because the percolator moved to a module it could no longer exist there. Instead of bringing it back it was removed. This validation existed since the percolator cache only supported one percolator query per document, since the percolator cache has been removed this restriction could removed as well.
* While moving percolator tests to the new module, also removed a couple of tests for the deprecated percolate and mpercolate api. These APIs are now sugar  APIs for bwc and rediect to the searvh and msearvh APIs. Some tests were still testing as if percolate and mpercolate API did the percolation, but this no longer the case and these tests could be removed.
