The Elasticsearch-JS client only produces documentation for major
versions (e.g., n.x, 7.x, 6.x).
However, the `{jsclient}` attribute uses the current `{branch}`, which
can result in broken links in minor version docs.
This swaps the `{jsclient}` attribute for `{jsclient-current}`,
which is less likely to break across versions.

This adds an API for simulating template composition with or without an index template.
It looks like:
```
POST /_index_template/_simulate/my-template
```
To simulate a template named `my-template` that already exists, or, to simulate a template that does
not already exist:
```
POST /_index_template/_simulate
{
"index_patterns": ["my-index"]
"composed_of": ["ct1", "ct2"],
}
```
This is related to #55686, which adds an API to simulate composition based on an index name (hence
the `_simulate_index` vs `_simulate`).
This commit also adds reference documentation for both simulation APIs.

Throttling nightly cleanup as much as we do has been over cautious.
Night cleanup should be more lenient in its throttling. We still
keep the same batch size, but now the requests per second scale
with the number of data nodes. If we have more than 5 data nodes,
we don't throttle at all.
Additionally, the API now has `requests_per_second` and `timeout` set.
So users calling the API directly can set the throttling.
This commit also adds a new setting `xpack.ml.nightly_maintenance_requests_per_second`.
This will allow users to adjust throttling of the nightly maintenance.
In #39466 we removed all the settings in the `discovery.zen` namespace in 8.0
and documented their removal as a breaking change. Conspicuously absent from
the list of removed settings is the `discovery.zen.minimum_master_nodes`
setting, and there are two other omitted settings and a duplicated one too.
This commit fixes up these docs.
Reworks the `from / size` content to `Paginate search results`.
Moves those docs from the request body search API page (slated for
deletion) to the `Run a search` tutorial docs.
Also adds some notes to the `from` and `size` param docs.

This adds support for `terms` and `rare_terms` aggs in transforms.
The default behavior is that the results are collapsed in the following manner:
`<AGG_NAME>.<BUCKET_NAME>.<SUBAGGS...>...`
Or if no sub aggs exist
`<AGG_NAME>.<BUCKET_NAME>.<_doc_count>`
The mapping is also defined as `flattened` by default. This is to avoid field explosion while still providing (limited) search and aggregation capabilities.
This commit removes the ability to put V2 index templates that reference missing component templates.
It also prevents removing component templates that are being referenced by an existing V2 index
template.

This aggregation will perform normalizations of metrics
for a given series of data in the form of bucket values.
The aggregations supports the following normalizations
- rescale 0-1
- rescale 0-100
- percentage of sum
- mean normalization
- z-score normalization
- softmax normalization
To specify which normalization is to be used, it can be specified
in the normalize agg's `normalizer` field.
For example:
```
{
"normalize": {
"buckets_path": <>,
"normalizer": "percent"
}
}
```
Closes#51005.

This optional parameter can only be a string. To test out a transient custom
analysis chain, users are expected to use the 'tokenizer', 'filter', and
'char_filter' parameters.
Today we report some statistics in terms of Lucene-level documents, which
differ from Elasticsearch-level documents in a number of ways and include
things like document tombstones which users cannot directly observe. This
commit clarifies the internal nature of these statistics.
Closes#56497
This adds a few things to the `breakdown` of the profiler:
* `histogram` aggregations now contain `total_buckets` which is the
count of buckets that they collected. This could be useful when
debugging a histogram inside of another bucketing agg that is fairly
selective.
* All bucketing aggs that can delay their sub-aggregations will now add
a list of delayed sub-aggregations. This is useful because we
sometimes have fairly involved logic around which sub-aggregations get
delayed and this will save you from having to guess.
* Aggregtations wrapped in the `MultiBucketAggregatorWrapper` can't
accurately add anything to the breakdown. Instead they the wrapper
adds a marker entry `"multi_bucket_aggregator_wrapper": true` so we
can be quickly pick out such aggregations when debugging.
It also fixes a bug where `_count` breakdown entries were contributing
to the overall `time_in_nanos`. They didn't add a large amount of time
so it is unlikely that this caused a big problem, but I was there.
To support the arbitrary breakdown data this reworks the profiler so
that the `breakdown` can contain any data that is supported by
`StreamOutput#writeGenericValue(Object)` and
`XContentBuilder#value(Object)`.
The docs pattern url was using `*` which means zero or many instead
of `?` which means zero or one. The pattern url returned in error
messages was not in sync with the one in the docs.
Fixes: #56476
