The shard follow task cleaner executes on behalf of the user to clean up
a shard follow task after the follower index has been
deleted. Otherwise, these persistent tasks are left laying around, and
they fail to execute because the follower index has been deleted. In the
face of security, attempts to complete these persistent tasks would
fail. This is because these cleanups are executed under the system
context (this makes sense, they are happening on behalf of the user
after the user has executed an action) but the system role was never
granted the permission for persistent task completion. This commit
addresses this by adding this cluster privilege to the system role.
Reading the startup scripts does not elucidate how JVM options are
applied. Instead, the reader must consult the source for the JVM options
parser. This commit adds some transparency around this process so that
it easier to understand reading the startup scripts how the final JVM
options to start Elasticsearch are constructed.
We marked the `init` ILM step as retryable but our test used `waitUntil`
without an assert so we didn’t catch the fact that we were not actually
able to retry this step as our ILM state didn’t contain any information
about the policy execution (as we were in the process of initialising
it).
This commit manually sets the current step to `init` when we’re moving
the ilm policy into the ERROR step (this enables us to successfully
move to the error step and later retry the step)

The oss and default bats tests were removed, but these references to
them remained, causing gradle failures when trying to run packaging
tests. While the upgrade and plugins bats tests should still be tested,
that is being handled in #51565. This commit removes the outdated
references.

* Set default ES_PATH_CONF for package scriptlets
Our packages use scriptlets to create or update the Elasticsearch
keystore as necessary when installing or upgrading an Elasticsearch
package. If these scriptlets don't work as expected, Elasticsearch may
try and fail to create or upgrade the keystore at startup time. This
will prevent Elasticsearch from starting up at all.
These scriptlets use the Elasticsearch keystore command-line tools. Like
most of our command-line tools, the keystore tools will by default get
their value for ES_PATH_CONF from a system configuration file:
/etc/sysconfig/elasticsearch for RPMs, /etc/default/elasticsearch for
debian packages. Previously, if the user removed ES_PATH_CONF from that
system configuration file (perhaps thinking that it is obsolete when
the same variables is also defined in the systemd unit file), the
keystore command-line tools would fail. Scriptlet errors do not seem to
cause the installation to fail, and for RPMs the error message is easy
to miss in command output.
This commit adds a line of bash to scriptlets that will set ES_PATH_CONF
to a default when ES_PATH_CONF is unset, rather than only when the
system configuration file is missing.

* Filter empty lines from docker ls response
In order to cut down on test time, our docker/vagrant tests build the
docker image outside of the vagrant VM. When we get around to launching
the Vagrant VM, we mount that already-built docker image to a known
location. At that point, we need to load the docker image. But we only
want to load it once. As we're running tests, we use "docker ls" to
check whether the local image is loaded for use. Empty output from the
particular ls invocation means no image is loaded.
There was a bug in how we checked this. In Java, splitting an empty
string will yield an array containing one empty string. So when we're
counting the output from the docker ls command, we need to filter out
empty lines in order to proceed to loading the image for docker tests.
The `top_metrics` agg is kind of like `top_hits` but it only works on
doc values so it *should* be faster.
At this point it is fairly limited in that it only supports a single,
numeric sort and a single, numeric metric. And it only fetches the "very
topest" document worth of metric. We plan to support returning a
configurable number of top metrics, requesting more than one metric and
more than one sort. And, eventually, non-numeric sorts and metrics. The
trick is doing those things fairly efficiently.

ML mappings and index templates have so far been created
programmatically. While this had its merits due to static typing,
there is consensus it would be clear to maintain those in json files.
In addition, we are going to adding ILM policies to these indices
and the component for a plugin to register ILM policies is
`IndexTemplateRegistry`. It expects the templates to be in resource
json files.
For the above reasons this commit refactors ML mappings and index
templates into json resource files that are registered via
`MlIndexTemplateRegistry`.

Fixes the the no-query optimization for `min` and `max` aggregations

This commit makes the names of fetch subphases more consistent:
* Now the names end in just 'Phase', whereas before some ended in
'FetchSubPhase'. This matches the query subphases like AggregationPhase.
* Some names include 'fetch' like FetchScorePhase to avoid ambiguity about what
they do.
Ironically PreventFailingBuildIT.testSoThatTestsDoNotFail is causing failures
as documented in #52197. The no longer serves a purpose and can now be removed.
This is to support the ML categorization wizard.
Currently cluster:admin/analyze is only provided with the
"manage" cluster privilege, which is an excessive privilege
level to provide access to this single feature. It means
that the ML categorization wizard only works for extremely
highly privileged users.
Following this change the Kibana system user will be
permitted to run the _analyze endpoint on supplied strings
(not on an index). The ML UI will then call the _analyze
endpoint as the Kibana system user after first checking
that the logged-in user is permitted to create an ML job.
This will mean that users with the more reasonable
"manage_ml" cluster privilege will be permitted to use
the ML categorization wizard.
(This is also consistent with the way the ML UI will access
_all_ Elasticsearch functionality when the "ML in Spaces"
project is completed.)

This adds a builder and parsed results for the `string_stats`
aggregation directly to the high level rest client. Without this the
HLRC can't access the `string_stats` API without the elastic licensed
`analytics` module.
While I'm in there this adds a few of our usual unit tests and
modernizes the parsing.
The example of how to access the nano value of a date_nanos field has
been broken since it was created. This commit fixes it to use the
correct scripting methods.

When `date_histogram` attempts to optimize itself it for a particular
time zone it checks to see if the entire shard is within the same
"transition". Most time zone transition once every size months or
thereabouts so the optimization can usually kicks in.
*But* it crashes when you attempt feed it a time zone who's last DST
transition was before epoch. The reason for this is a little twisted:
before this patch it'd find the next and previous transitions in
milliseconds since epoch. Then it'd cast them to `Long`s and pass them
into the `DateFieldType` to check if the shard's contents were within
the range. The trouble is they are then converted to `String`s which are
*then* parsed back to `Instant`s which are then convertd to `long`s. And
the parser doesn't like most negative numbers. And everything before
epoch is negative.
This change removes the
`long` -> `Long` -> `String` -> `Instant` -> `long` chain in favor of
passing the `long` -> `Instant` -> `long` which avoids the fairly complex
parsing code and handles a bunch of interesting edge cases around
epoch. And other edge cases around `date_nanos`.

We need to reduce the translog sync interval for indices with translog
async setting so that we can have the safe commit in the assertBusy
interval. This is needed since #51905, where we use the local checkpoint
of the safe commit to calculate the number of uncommitted operations of
a translog stats.

Add a new cluster setting `search.allow_expensive_queries` which by
default is `true`. If set to `false`, certain queries that have
usually slow performance cannot be executed and an error message
is returned.
- Queries that need to do linear scans to identify matches:
- Script queries
- Queries that have a high up-front cost:
- Fuzzy queries
- Regexp queries
- Prefix queries (without index_prefixes enabled
- Wildcard queries
- Range queries on text and keyword fields
- Joining queries
- HasParent queries
- HasChild queries
- ParentId queries
- Nested queries
- Queries on deprecated 6.x geo shapes (using PrefixTree implementation)
- Queries that may have a high per-document cost:
- Script score queries
- Percolate queries

The buffer in LoggingOutputStream skips flushing when only a newline
appears. However, if a windows newline appeared, the buffer length was
not reset. This commit resets the length so the \r does not appear in
the next logging message.

* Add more checks around parameter conversions
This commit adds two necessary verifications on received parameters:
- it checks the validity of the parameter's data type: if the declared
data type is resolved to an ES or Java type;
- it checks if the returned converter is non-null (i.e. a conversion is
possible) and generates an appropriate exception otherwise.

Move EC2 discovery tests to using the mock REST API introduced in
https://github.com/elastic/elasticsearch/pull/50550 instead of mocking
the AWS SDK classes manually.
Move the trivial remaining AWS SDK mocks to the single test suit that
was using them.
MockRandomMergePolicy randomly determines if a segment should use a
compound format. This can cause a force merge performing two merges: (1)
merging to a single segment, (2) rewriting the new segment using the
compound format. If the second merge completes after we have flushed,
then it can flip the flag shouldPeriodicallyFlushAfterBigMerge to true.
