[DOCS] Remove heading offsets for REST APIs (#44568) Several files in the REST APIs nav section are included using :leveloffset: tags. This increments headings (h2 -> h3, h3 -> h4, etc.) in those files and removes the :leveloffset: tags. Other supporting changes: * Alphabetizes top-level REST API nav items. * Change 'indices APIs' heading to 'index APIs.' * Changes 'Snapshot lifecycle management' heading to sentence case.

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

Rename the bulk thread pool to write thread pool (#29593) This commit renames the bulk thread pool to the write thread pool.

With this change, we add support for fallback settings thread_pool.bulk.* which will be supported until 7.0.0.

Add support for documented byte/size units and for micros as a time unit in _cat API We advertise in our documentation that byte units are like `kb`, `mb`... But we actually only support the simple notation `k` or `m`. This commit adds support for the documented form and keeps the non documented options to avoid any breaking change. It also adds support for `micros`, `nanos` and `d` as a time unit in `_cat` API. Remove the support for `b` as a SizeValue unit. Actually, for numbers, when using raw numbers without unit, there is no text to add/parse after the number. For example, you don't write `10` as `10b`. We support option like `size=` in `_cat` API which means that we want to display raw data without unit (singles). Documentation updated accordingly. Add test for the empty size option.

or a time value. By default, these types are human-formatted,

for example, `3.5mb` instead of `3763212`. The human values are not
sortable numerically, so in order to operate on these values where
order is important, you can change it.
Say you want to find the largest index in your cluster (storage used
by all the shards, not number of documents). The `/_cat/indices` API
is ideal. We only need to tweak two things. First, we want to turn
off human mode. We'll use a byte-level resolution. Then we'll pipe
our output into `sort` using the appropriate column, which in this

This is in opposition to the HTTP spec which specifies the Accept header field for this purpose. This commit replaces the use of the Content-Type header field with the Accept header field in the cat API. Closes #14421

[DOCS] Remove heading offsets for REST APIs (#44568) Several files in the REST APIs nav section are included using :leveloffset: tags. This increments headings (h2 -> h3, h3 -> h4, etc.) in those files and removes the :leveloffset: tags. Other supporting changes: * Alphabetizes top-level REST API nav items. * Change 'indices APIs' heading to 'index APIs.' * Changes 'Snapshot lifecycle management' heading to sentence case.

Each of the commands accepts a query string parameter `s` which sorts the table by
the columns specified as the parameter value. Columns are specified either by name or by
alias, and are provided as a comma separated string. By default, sorting is done in
ascending fashion. Appending `:desc` to a column will invert the ordering for
that column. `:asc` is also accepted but exhibits the same behavior as the default sort order.
For example, with a sort string `s=column1,column2:desc,column3`, the table will be
sorted in ascending order by column1, in descending order by column2, and in ascending
order by column3.

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
