Ryan Ernst 6940b2b8c7 Remove groovy scripting language (#21607)
* Scripting: Remove groovy scripting language

Groovy was deprecated in 5.0. This change removes it, along with the
legacy default language infrastructure in scripting.

Nik Everett 1791623700 Document `error_trace`
The `error_trace` parameter turns on the `stack_trace` field
in errors which returns stack traces.

Removes documentation for `camelCase` because it hasn't worked
in a while....

Documents the internal parameters used to render stack traces as
internal only.

Closes #21708

Luca Cavanna db5a72774b Add indices and filter information to search shards api output (#21738)
Add indices and filter information to search shards api output

The search shards api returns info about which shards are going to be hit by executing a search with provided parameters: indices, routing, preference. Indices can also be aliases, which can also hold filters. The output includes an array of shards and a summary of all the nodes the shards are allocated on. This commit adds a new indices section to the search shards output that includes one entry per index, where each index can be associated with an optional filter in case the index was hit through a filtered alias.

This is relevant since we have moved parsing of alias filters to the coordinating node.

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 457c2d8fb0 Add Debug.explain to painless
You can use `Debug.explain(someObject)` in painless to throw an
`Error` that can't be caught by painless code and contains an
object's class. This is useful because painless's sandbox doesn't
allow you to call `someObject.getClass()`.

Closes #20263

Luca Cavanna db8b2dceea Remove ignored type parameter in search_shards api (#21688)
The `type` parameter has always been accepted by the search_shards api, probably to make the api and its urls the same as search. Truth is that the type never had any effect, it's been ignored from day one while accepting it may make users think that we actually do something with it.

This commit removes support for the type parameter from the REST layer and the Java API. Backwards compatibility is maintained on the transport layer though.

The new added serialization test also uncovered a bug in the java API where the `ClusterSearchShardsRequest` could be created with no arguments, but the indices were required to be not null otherwise the request couldn't be serialized as `writeTo` would throw NPE. Fixed by setting a default value (empty array) for indices.

Lee Hinman 11da09e9bc Allow overriding all-field leniency when `lenient` option is specified
As part of #20925 and #21341 we added an "all-fields" mode to the
`query_string` and `simple_query_string`. This would expand the query to
all fields and automatically set `lenient` to true.

However, we should still allow a user to override the `lenient` flag to
whichever value they desire, should they add it in the request. This
commit does that.

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.

ismael-hasan 7906db83d5 Update BulkProcessor size in the example
By default, it is recommended to start bulk with a size of 10-15MB, and increase it gradually to get the right size for the environment. The example shows originally 1GB, which can lead to some users to just copy-paste the code snippet and start with excessively big sizes.

Tal Levy 04b712bdc5 fix trace_match behavior for when there is only one grok pattern (#21413)
There is an issue in the Grok Processor, where trace_match: true does not inject the _ingest._grok_match_index into the ingest-document when there is just one pattern provided. This is due to an optimization in the regex construction. This commit adds a check for when this is the case, and injects a static index value of "0", since there is only one pattern matched (at the first index into the patterns).

To make this clearer, more documentation was added to the grok-processor docs.

Fixes #21371.

Adrien Grand 6db683a4bd Fix recurring doc test failures with the cat API. (#21561)
This failure is due to the fact that we sort on store size, which is cached. So

one, which makes the indices sorted in the wrong order. This changes the doc
example to sort on the number of docs instead.
