This commit updates the s3 repository docs to clearly mark settings as
part of the s3 client settings, as well as those that are secure and
must be stored in the elasticsearch keystore.

The s3 repository plugin has "third party" integ tests which rely
on external service and configuration setup. These tests are really
internal verification of the plugin (and should be moved to real integ
tests). Running them is not something a user should do, and the
documentation has been out of date for all of 5.x. This commit removes
the docs, removing potential confusion for users.
This commit adds a small note to the discovery docs to include a note
that we recommend that the unicast hosts list be maintained as the list
of master-eligible nodes in the cluster.

This commit updates the docs for the config files to explain the new
mechanism for customizing the configuration directory via the
environment variable CONF_DIR.

We publish javadocs to artifacts.elastic.co (and snapshots.elastic.co) for a while. This commit adds the link to them to the transport client, low level REST client, sniffer and high level REST client pages.
Closes#23761
This commit removes an outdated reference to http_address in the nodes
info docs. This information is available in the http object for each
node in the nodes info API response.

On non-Windows platforms, we ignore the environment variable
JAVA_TOOL_OPTIONS (this is an environment variable that the JVM respects
by default for picking up extra JVM options). The primary reason that we
ignore this because of the Jayatana agent on Ubuntu; a secondary reason
is that it produces an annoying "Picked up JAVA_TOOL_OPTIONS: ..."
output message. When the elasticsearch-env batch script was introduced
for Windows, ignoring this environment variable was deliberately not
carried over as the primary reason does not apply on Windows. However,
after additional thinking, it seems that we should simply be consistent
to the extent possible here (and also avoid that annoying "Picked up
JAVA_TOOL_OPTIONS: ..." on Windows too). This commit causes the Windows
version of elasticsearch-env to also ignore JAVA_TOOL_OPTIONS.

This commit adds a bootstrap check for the maximum file size, and
ensures the limit is set correctly when Elasticsearch is installed as a
service on systemd-based systems.

The Writeble representation is less heavy to parse and that will benefit percolate performance and throughput.
The query builder's binary format has now the same bwc guarentees as the xcontent format.
Added a qa test that verifies that percolator queries written in older versions are still readable by the current version.
The example output for node info and cluster stats was outdated w.r.t.
to the information that is shown for plugins. With this commit we
updated the example output and update the explanation of the respective
fields.
This commit changes the way we handle field expansion in `match`, `multi_match` and `query_string` query.
The main changes are:
- For exact field name, the new behavior is to rewrite to a matchnodocs query when the field name is not found in the mapping.
- For partial field names (with `*` suffix), the expansion is done only on `keyword`, `text`, `date`, `ip` and `number` field types. Other field types are simply ignored.
- For all fields (`*`), the expansion is done on accepted field types only (see above) and metadata fields are also filtered.
- The `*` notation can also be used to set `default_field` option on`query_string` query. This should replace the needs for the extra option `use_all_fields` which is deprecated in this change.
This commit also rewrites simple `*` query to matchalldocs query when all fields are requested (Fixes#25556).
The same change should be done on `simple_query_string` for completeness.
`use_all_fields` option in `query_string` is also deprecated in this change, `default_field` should be set to `*` instead.

This commit adds the min wire/index compat versions to the main action
output. Not only will this make the compatility expected more
transparent, but it also allows to test which version others think the
compat versions are, similar to how we test the lucene version.
When a node tries to join a cluster, it goes through a validation step to make sure the node is compatible with the cluster. Currently we validation that the node can read the cluster state and that it is compatible with the indexes of the cluster. This PR adds validation that the joining node's version is compatible with the versions of existing nodes. Concretely we check that:
1) The node's min compatible version is higher or equal to any node in the cluster (this prevents a too-new node from joining)
2) The node's version is higher or equal to the min compat version of all cluster nodes (this prevents a too old join where, for example, the master is on 5.6, there's another 6.0 node in the cluster and a 5.4 node tries to join).
3) The node's major version is at least as higher as the lowest node in the cluster. This is important as we use the minimum version in the cluster to stop executing bwc code for operations that require multiple nodes. If the nodes are already operating in "new cluster mode", we should prevent nodes from the previous major to join (even if they are wire level compatible). This does mean that if you have a very unlucky partition during the upgrade which partitions all old nodes which are also a minority / data nodes only, the may not be able to re-join the cluster. We feel this edge case risk is well worth the simplification it brings to BWC layers only going one way. This restriction only holds if the cluster state has been recovered (i.e., the cluster has properly formed).
Also, the node join validation can now selectively fail specific nodes (previously the entire batch was failed). This is an important preparation for a follow up PR where we plan to have a rejected joining node die with dignity.
Also has updates to ScriptMetaData for allowing the old namespace format to be loaded all the way back through 5.0; however, it will throw an exception if two scripts share the same id but different languages.
This commit calls the `useSystemProperties` method on the HttpAsyncClientBuilder so that the jvm
system properties are used. The primary reason for doing this is to ensure the builder uses the
system default SSLContext rather than the default instance created by the http client library.
Closes#23231
Today we enable users to customize the environment through the use of
ES_INCLUDE. This made sense for legacy reasons when we did not have
nicities like jvm.options (so dumped JVM options in the default include
script) and somewhat duplicates some of the functionality that we will
need from a dedicated environment script. This commit removes support
for ES_INCLUDE as a first step towards a dedicated include script.

We currently use fielddata on the `_id` field which is trappy, especially as we
do it implicitly. This changes the `random_score` function to use doc ids when
no seed is provided and to suggest a field when a seed is provided.
For now the change only emits a deprecation warning when no field is supplied
but this should be replaced by a strict check on 7.0.

This commit expands on the migration note regarding the removal of
default.path.data and default.path.logs to include a note that users
that were relying on the defaults (the common case for path.logs), and
they carry over their previous elasticsearch.yml configruation file,
then they must add explicit values for path.data and path.logs.
