* Add parent-join module
This change adds a new module named `parent-join`.
The goal of this module is to provide a replacement for the `_parent` field but as a first step this change only moves the `has_child`, `has_parent` queries and the `children` aggregation to this module.
These queries and aggregations are no longer in core but they are deployed by default as a module.

In windows we can't reliable git the pid so we skip the
reindex-from-remote tests from old versions of elasticsearch. This
is OK because we aren't really testing windows here anyway. It isn't
great, but should be safe.
Two of the versions of Elasticsearch we need to run for these tests
can't run in Java 9 so we skip the entire test if we are running in
java 9. For now. I'd like to reenable it to run against java 8 if
there is one available, but that can wait for another time.

Adds tests for reindex-from-remote for the latest 2.4, 1.7, and
0.90 releases. 2.4 and 1.7 are fairly popular versions but 0.90
is a point of pride.
This fixes any issues those tests revealed.

This commit renames ScriptEngineService to ScriptEngine. It is often
confusing because we have the ScriptService, and then
ScriptEngineService implementations, but the latter are not services as
we see in other places in elasticsearch.
File scripts have 2 related settings: the path of file scripts, and
whether they can be dynamically reloaded. This commit deprecates those
settings.

Today we rely on background syncs to relay the global checkpoint under
the mandate of the primary to its replicas. This means that the global
checkpoint on a replica can lag far behind the primary. The commit moves
to inlining global checkpoints with replication requests. When a
replication operation is performed, the primary will send the latest
global checkpoint inline with the replica requests. This keeps the
replicas closer in-sync with the primary.
However, consider a replication request that is not followed by another
replication request for an indefinite period of time. When the replicas
respond to the primary with their local checkpoint, the primary will
advance its global checkpoint. During this indefinite period of time,
the replicas will not be notified of the advanced global
checkpoint. This necessitates a need for another sync. To achieve this,
we perform a global checkpoint sync when a shard falls idle.

Previously, Mustache would call `toString` on the `_ingest.timestamp`
field and return a date format that did not match Elasticsearch's
defaults for date-mapping parsing. The new ZonedDateTime class in Java 8
happens to do format itself in the same way ES is expecting.
This commit adds support for a feature flag that enables the usage of this new date format
that has more native behavior.
Fixes#23168.
This new fix can be found in the form of a cluster setting called
`ingest.new_date_format`. By default, in 5.x, the existing behavior
will remain the same. One will set this property to `true` in order to
take advantage of this update for ingest-pipeline convenience.
When installing plugin permissions, we try to set the permissions on all
installed files ourselves because a umask from the user could violate
everything needed to get the permissions right. Sadly, directories were
not handled correctly at all and so we were still left with broken
installations with umasks like 0077. This commit fixes this issue, adds
a thorough unit test for the situation, and most importantly, adds a
test that sets the umask before installing the plugin.

The license header in this file was after and on the same line as the
package statement. This commit moves the package statement to be after
the license header.
Netty uses the number of processors for sizing various resources (e.g.,
thread pools, buffer pools, etc.). However, it uses the runtime number
of available processors which might not match the configured number of
processors as set in Elasticsearch to limit the number of threads (for
example, in Docker containers). A new feature was added to Netty that
enables configuring the number of processors Netty should see for sizing
this various resources. This commit takes advantage of this feature to
set this number of available processors to be equal to the configured
number of processors set in Elasticsearch.

The tribe service can take a while to initialize, depending on how many cluster it needs to connect to. This change moves writing the ports file used by tests to before the tribe service is started.
This adds the `index.mapping.single_type` setting, which enforces that indices
have at most one type when it is true. The default value is true for 6.0+ indices
and false for old indices.

The bats tests are descructive and must be run as root. This is a
horrible combination on any sane system but perfectly fine to do
in a VM. This change modifies the tests so they revuse to start
unless they are in an environment with an `/etc/is_vagrant_vm`
file. The Vagrantfile creates it on startup.
Closes#24137
If the user explicitly configured path.data to include
default.path.data, then we should not fail the node if we find indices
in default.path.data. This commit addresses this.

In #24251 we fix an issue with stored search templates that
this test would have discovered: stored search templates cause
the node to refuse to start. Technically a "restart" test would
have caught this as well and would have caught it more quickly.
But we already *have* an upgrade test and we don't have restart tests.
And testing this on upgrade is a good thing too.
It seems that Wildfly 10 can not be made to start in a fully-functional
form on JDK 9, so this commit skips running the Wildfly integration
tests on JDK 9.
An important use case for our users is deploying our clients inside of
applications containers like Wildly. Sometimes, we make changes that
unintentionally break this use case. We need to know before we ship a
release that we have broken such use cases. As Wildfly is one of the
bigger application containers, this commit starts by adding an
integration test that deploys an application using the transport client
to Wildfly and ensures that all is well. Future work can add similar
integration tests for the low-level and high-level REST clients.

The plugin cli currently resides inside the elasticsearch jar. This
commit moves it into a plugin-cli jar. This is change alone is a no-op;
it does not change anything about what is loaded at runtime. But it will
allow easier testing (with fixtures in the future to test ES or maven
installation), as well as eventually not loading these classes when
starting elasticsearch.
This leniency was left in after plugin installer refactoring for 2.0
because some tests still relied on it. However, the need for this
leniency no longer exists.
* Replicate write failures
Currently, when a primary write operation fails after generating
a sequence number, the failure is not communicated to the replicas.
Ideally, every operation which generates a sequence number on primary
should be recorded in all replicas.
In this change, a sequence number is associated with write operation
failure. When a failure with an assinged seqence number arrives at a
replica, the failure cause and sequence number is recorded in the translog
and the sequence number is marked as completed via executing `Engine.noOp`
on the replica engine.

depanding on it's primary execution
* remove bulk shard result abstraction
* fix failure handling logic for bwc
* add more tests
* minor fix
* cleanup
* incorporate feedback
* incorporate feedback
* add assert to remove handling noop primary response when 5.0 nodes are not supported
This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.

After splitting integ tests into cluster configuration and the test
runner task, we still have dependencies of the test runner added as deps
of the cluster. This commit adds dependencies directly to the cluster,
so that the runner can have other dependencies independent of what is
needed for the cluster.
We have some packaging tests where we use a custom jvm.options file. The
flags we use here are barebones, just enough to exercise that using a
custom jvm.options files actually works. Due to this, we are missing a
Log4j flag that prevents Log4j from trying to use JMX. If Log4j tries to
use JMX, it hits a security manager exception and tries to log
this. This attempt to log happens before we've configured
logging. Previously, Elasticsearch was lenient here so this was treated
as harmless and the test could march on. Now, we fail startup if we
detect an attempt to log before logging is configured so this prevents
Elasticsearch from starting if we do not have jvm.options files in place
that prevent these log messages from being written before logging is
being configured. This commit adds jvm.options files in the places need
to prevent this.
These tests were marked as awaits fix due to JNA requiring a version of
glibc greater than or equal to version 2.14. Since we still support
systems that would not have this version, we have released our own JNA
dependency that is built to support earlier versions of glibc. This
commit removes some await fixes that were added to tests that failed as
a result of this situation.
It can easily happen that we touch a logger before logging is configured
due to chains of static intializers and other such scenarios. This
commit adds detection for this mechanism that will fail startup if we
touch a logger before logging is configured. This is a bug that will
cause builds to fail.

This is related to #23893. This commit allows users to use wilcards for
cluster names when executing a cross cluster search.
So instead of defining every cluster such as:
GET one:*,two:*,three:*/_search
A user could just search:
GET *:*/_search
As ":" characters are currently allowed in index names, if the text
up to the first ":" does not match a defined cluster name, the entire
string is treated as an index name.
All our actions that are invoked from rest actions have corresponding
transport actions. This adds the transport action for RestRemoteClusterInfoAction
for consistency.

This commit fixes the handling of POSIX permissions on Windows in the
spawner tests. Since POSIX permissions do not exist there, we first have
to check if we are on a filesystem that supports POSIX or not before
attempting to set the permissions.
This commit renames the random ASCII helper methods in ESTestCase. This
is because this method ultimately uses the random ASCII methods from
randomized runner, but these methods actually only produce random
