Detach Transport from TransportService (#31727)
Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper 
callback interface.

This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.

[ML] Limit ML filter items to 10K (#31731)
Add hard limit to the number of items
a filter may have. This serves to protect
from excessive overhead due to the filters
taking too much memory or lookups becoming
too expensive.

[ML] Return statistics about forecasts as part of the jobsstats and usage API (#31647)
This change adds stats about forecasts, to the jobstats api as well as xpack/_usage. The following 
information is collected:

_xpack/ml/anomaly_detectors/{jobid|_all}/_stats:

 -  total number of forecasts
 -  memory statistics (mean/min/max)
 -  runtime statistics
 -  record statistics
 -  counts by status

_xpack/usage

 -  collected by job status as well as overall (_all):
     -  total number of forecasts
     -  number of jobs that have at least 1 forecast
     -  memory, runtime, record statistics
     -  counts by status

Fixes #31395

resolveHasher defaults to NOOP (#31723)
* Default resolveFromHash to Hasher.NOOP

This changes the default behavior when resolving the hashing
algorithm from unrecognised hash strings, which was introduced in
 #31234

A hash string that doesn't start with an algorithm identifier can
either be a malformed/corrupted hash or a plaintext password when
Hasher.NOOP is used(against warnings).
Do not make assumptions about which of the two is true for such
strings and default to Hasher.NOOP. Hash verification will subsequently
fail for malformed hashes.
Finally, do not log the potentially malformed hash as this can very
well be a plaintext password.

Support multiple system store types (#31650)
Support multiple system store types

When falling back to using the system keystore and - most usually -
truststore, do not assume that it will be a JKS store, but deduct
its type from {@code KeyStore#getDefaultKeyStoreType}. This allows
the use of any store type the Security Provider supports by setting
the keystore.type java security property.

Configurable password hashing algorithm/cost (#31234)
Make password hashing algorithm/cost configurable for the 
stored passwords of users for the realms that this applies
(native, reserved). Replaces predefined choice of bcrypt with
cost factor 10.
This also introduces PBKDF2 with configurable cost
(number of iterations) as an algorithm option for password hashing
both for storing passwords and for the user cache.
Password hash validation algorithm selection takes into
consideration the stored hash prefix and only a specific number
of algorithnm and cost factor options for brypt and pbkdf2 are 
whitelisted and can be selected in the relevant setting.

Upgrade gradle wrapper to 4.8 (#31525)
* Move to Gradle 4.8 RC1

* Use latest version of plugin

The current does not work with Gradle 4.8 RC1

* Switch to Gradle GA

* Add and configure build compare plugin

* add work-around for https://github.com/gradle/gradle/issues/5692

* work around https://github.com/gradle/gradle/issues/5696

* Make use of Gradle build compare with reference project

* Make the manifest more compare friendly

* Clear the manifest in compare friendly mode

* Remove animalsniffer from buildscript classpath

* Fix javadoc errors

* Fix doc issues

* reference Gradle issues in comments

* Conditionally configure build compare

* Fix some more doclint issues

* fix typo in build script

* Add sanity check to make sure the test task was replaced

Relates to #31324. It seems like Gradle has an inconsistent behavior and
the taks is not always replaced.

* Include number of non conforming tasks in the exception.

* No longer replace test task, create implicit instead

Closes #31324. The issue has full context in comments.

With this change the `test` task becomes nothing more than an alias for `utest`.
Some of the stand alone tests that had a `test` task now have `integTest`, and a
few of them that used to have `integTest` to run multiple tests now only
have `check`.
This will also help separarate unit/micro tests from integration tests.

* Revert "No longer replace test task, create implicit instead"

This reverts commit f1ebaf7d93e4a0a19e751109bf620477dc35023c.

* Fix replacement of the test task

Based on information from gradle/gradle#5730 replace the task taking
into account the task providres.
Closes #31324.

* Only apply build comapare plugin if needed

* Make sure test runs before integTest

* Fix doclint aftter merge

* PR review comments

* Switch to Gradle 4.8.1 and remove workaround

* PR review comments

* Consolidate task ordering

QA: Create xpack yaml features (#31403)
This creates a YAML test "features" that indices if the cluster being
tested has xpack installed (`xpack`) or if it does *not* have xpack
installed (`no_xpack`). It uses those features to centralize skipping
a few tests that fail if xpack is installed.

The plan is to use this in a followup to skip docs tests that require
xpack when xpack is not installed. We *plan* to use the declaration
of required license level on the docs page to generate the required
`skip`.

Closes #30933.

[ML] Add ML filter update API (#31437)
This adds an api to allow updating a filter:

POST _xpack/ml/filters/{filter_id}/_update

The request body may have:

- description: setting a new description
- add_items: a list of the items to add
- remove_items: a list of the items to remove

This commit also changes the PUT filter api to
error when the filter_id is already used. As
now there is an api for updating filters, the
put api should only be used to create new ones.

Also, updating a filter results into a notification
message auditing the change for every job that is
using that filter.

[Security] Check auth scheme case insensitively (#31490)
According to RFC 7617, the Basic authentication scheme name
should not be case sensitive.
Case insensitive comparisons are also applicable for the bearer
tokens where Bearer authentication scheme is used as per
RFC 6750 and RFC 7235

Some Http clients may send authentication scheme names in
different case types for eg. Basic, basic, BASIC, BEARER etc.,
so the lack of case-insensitive check is an issue when these
clients try to authenticate with elasticsearch.

This commit adds case-insensitive checks for Basic and Bearer
authentication schemes.

- POST _xpack/index_lifecycle/_stop
   - issues a request to be placed into STOPPED mode (maintenance mode).
     This is not immediate, since we must first verify that
     it is safe to go from STOPPING -> STOPPED.
- POST _xpack/index_lifecycle/_start
   - issues a request to be placed back into RUNNING mode (immediately)
- GET _xpack/index_lifecycle/_status
   - get back the current mode our lifecycle management is in

- update task was hardened to support uninstalled metadata
- if no metadata is installed, the start/stop actions will install metadata
  and proceed to try and change it (default start mode is RUNNING)
- rename MAINTENANCE -> STOPPED, MAINTENANCE_REQUESTED -> STOPPING, NORMAL -> RUNNING

inherit [index.lifecycle.date] from rolled-over time (#30853)
Indices that are rolled over preserve their origin index.lifecycle.date
as the time the index was created. Although this is also fine, it would
make more sense to start the timer for moving to the warm phase from the
time it was rolled over so that we capture the time elapsed from the
latest data, as opposed to when the index was created.

This commit adds an extra step within the RolloverAction that
extracts the index.creation_date of the newly created index from the RolloverStep
and sets that as the index.lifecycle.date of the rolled-over index that is
waiting for its next phase.

Introduce http and tcp server channels (#31446)
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).

Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.

Security: fix joining cluster with production license (#31341)
The changes made to disable security for trial licenses unless security
is explicitly enabled caused issues when a 6.3 node attempts to join a
cluster that already has a production license installed. The new node
starts off with a trial license and `xpack.security.enabled` is not
set for the node, which causes the security code to skip attaching the
user to the request. The existing cluster has security enabled and the
lack of a user attached to the requests causes the request to be
rejected.

This commit changes the security code to check if the state has been
recovered yet when making the decision on whether or not to attach a
user. If the state has not yet been recovered, the code will attach
the user to the request in case security is enabled on the cluster
being joined.

Unify http channels and exception handling (#31379)
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.

Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.

Use system context for cluster state update tasks (#31241)
This commit makes it so that cluster state update tasks always run under the system context, only
restoring the original context when the listener that was provided with the task is called. A notable
exception is the clusterStatePublished(...) callback which will still run under system context,
because it's defined on the executor-level, and not the task level, and only called once for the
combined batch of tasks and can therefore not be uniquely identified with a task / thread context.

Add byte array pooling to nio http transport (#31349)
This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.

Introduce Maintenance Mode to ILM (#31164)
This PR introduces a concept of a maintenance mode for the
lifecycle service. During maintenance mode, no policies are
executed.

To be placed into maintenance mode, users must first issue a
request to be placed in maintenance mode. Once the service
is assured that no policies are in actions that are not to be
interrupted (like ShrinkAction), the service will place itself
in maintenance mode.

APIs to-be introduced:

- POST _xpack/index_lifecycle/maintenance/_request
   - issues a request to be placed into maintenenance mode.
     This is not immediate, since we must first verify that
     it is safe to go from REQUESTED -> IN maintenance mode.
- POST _xpack/index_lifecycle/maintenance/_stop
   - issues a request to be taken out (this is immediate)
- GET _xpack/index_lifecycle/maintenance
   - get back the current mode our lifecycle management is in

[ML] Hold ML filter items in sorted set (#31338)
Filter items should be unique. They should also
be sorted to make them easier to read plus save
sorting in the autodetect process.

Move IndexLifecycleMetadata installation to put-lifecycle-action (#31346)
There is a problematic scenario with x-pack-cluster master-nodes
attempting to install custom metadata into the cluster-state and
broadcasting that to non-x-pack-enabled nodes. Since those nodes
are not aware of this custom metadata, their cluster-state recovery
will be broken. This change ensures that newly-elected x-pack master
nodes bootstrap IndexLifecycleMetadata upon the first request to
leverage its features. This means that PutLifecycleAction is
now responsible for installing the metadata. Since this X-Pack API
can only be called once all nodes in the cluster have x-pack enabled,
it is safe to assume that the cluster will appropriately handle the
cluster-state recovery with the new set of index-lifecycle metadata.

Uncouple persistent task state and status (#31031)
This pull request removes the relationship between the state 
of persistent task (as stored in the cluster state) and the status 
of the task (as reported by the Task APIs and used in various 
places) that have been confusing for some time (#29608).

In order to do that, a new PersistentTaskState interface is added. 
This interface represents the persisted state of a persistent task. 
The methods used to update the state of persistent tasks are 
renamed: updatePersistentStatus() becomes updatePersistentTaskState() 
and now takes a PersistentTaskState as a parameter. The 
Task.Status type as been changed to PersistentTaskState in all 
places were it make sense (in persistent task customs in cluster 
state and all other methods that deal with the state of an allocated 
persistent task).
