Added dedicated thread pool cat api, that can show all thread pool related statistic (size, rejected, queue etc.) for all thread pools (get, search, index etc.) By default active, rejected and queue thread statistics are included for the index, bulk and search thread pool. Other thread statistics of other thread pools can be included via the `h` query string parameter. Closes #4907

Improve cat thread pool API Today, when listing thread pools via the cat thread pool API, thread pools are listed in a column-delimited format. This is unfriendly to command-line tools, and inconsistent with other cat APIs. Instead, thread pools should be listed in a row-delimited format. Additionally, the cat thread pool API is limited to a fixed list of thread pools that excludes certain built-in thread pools as well as all custom thread pools. These thread pools should be available via the cat thread pool API. This commit improves the cat thread pool API by listing all thread pools (built-in or custom), and by listing them in a row-delimited format. Finally, for each node, the output thread pools are sorted by thread pool name. Relates #19721

Introduce analyze thread pool (#29541) We want to remove the index thread pool as it is no longer needed since single-document indexing requests are executed as bulk requests now. Analyze requests are also executed on the index thread pool though and they need a thread pool to execute on. The bulk thread does not seem like the right thread pool, let us keep that thread pool conceptually for bulk requests and free for bulk requests. None of the existing thread pools make sense for analyze requests either. The generic thread pool would be a terrible choice since it has an unbounded queue and that is a bad idea for user-facing APIs. This commit introduces a small by default (size=1, queue_size=16) thread pool for analyze requests.

Docs: Use the default distribution to test docs (#31251) This switches the docs tests from the `oss-zip` distribution to the `zip` distribution so they have xpack installed and configured with the default basic license. The goal is to be able to merge the `x-pack/docs` directory into the `docs` directory, marking the x-pack docs with some kind of marker. This is the first step in that process. This also enables `-Dtests.distribution` support for the `docs` directory so you can run the tests against the `oss-zip` distribution with something like ``` ./gradlew -p docs check -Dtests.distribution=oss-zip ``` We can set up Jenkins to run both.

Rename the bulk thread pool to write thread pool (#29593) This commit renames the bulk thread pool to the write thread pool. This is to better reflect the fact that the underlying thread pool is used to execute any document write request (single-document index/delete/update requests, and bulk requests). With this change, we add support for fallback settings thread_pool.bulk.* which will be supported until 7.0.0. We also add a system property so that the display name of the thread pool remains as "bulk" if needed to avoid breaking users.

// The substitutions do two things:
// 1. Expect any number of extra thread pools. This allows us to only list a
// few thread pools. The list would be super long otherwise. In addition,
// if xpack is installed then the list will contain more thread pools and
// this way we don't have to assert about them.
// 2. Expect any number of active, queued, or rejected items. We really don't
// know how many there will be and we just want to assert that there are
// numbers in the response, not *which* numbers are there.

Enforce that responses in docs are valid json (#26249) All of the snippets in our docs marked with `// TESTRESPONSE` are checked against the response from Elasticsearch but, due to the way they are implemented they are actually parsed as YAML instead of JSON. Luckilly, all valid JSON is valid YAML! Unfurtunately that means that invalid JSON has snuck into the exmples! This adds a step during the build to parse them as JSON and fail the build if they don't parse. But no! It isn't quite that simple. The displayed text of some of these responses looks like: ``` { ... "aggregations": { "range": { "buckets": [ { "to": 1.4436576E12, "to_as_string": "10-2015", "doc_count": 7, "key": "*-10-2015" }, { "from": 1.4436576E12, "from_as_string": "10-2015", "doc_count": 0, "key": "10-2015-*" } ] } } } ``` Note the `...` which isn't valid json but we like it anyway and want it in the output. We use substitution rules to convert the `...` into the response we expect. That yields a response that looks like: ``` { "took": $body.took,"timed_out": false,"_shards": $body._shards,"hits": $body.hits, "aggregations": { "range": { "buckets": [ { "to": 1.4436576E12, "to_as_string": "10-2015", "doc_count": 7, "key": "*-10-2015" }, { "from": 1.4436576E12, "from_as_string": "10-2015", "doc_count": 0, "key": "10-2015-*" } ] } } } ``` That is what the tests consume but it isn't valid JSON! Oh no! We don't want to go update all the substitution rules because that'd be huge and, ultimately, wouldn't buy much. So we quote the `$body.took` bits before parsing the JSON. Note the responses that we use for the `_cat` APIs are all converted into regexes and there is no expectation that they are valid JSON. Closes #26233

Improve cat thread pool API Today, when listing thread pools via the cat thread pool API, thread pools are listed in a column-delimited format. This is unfriendly to command-line tools, and inconsistent with other cat APIs. Instead, thread pools should be listed in a row-delimited format. Additionally, the cat thread pool API is limited to a fixed list of thread pools that excludes certain built-in thread pools as well as all custom thread pools. These thread pools should be available via the cat thread pool API. This commit improves the cat thread pool API by listing all thread pools (built-in or custom), and by listing them in a row-delimited format. Finally, for each node, the output thread pools are sorted by thread pool name. Relates #19721
