Add Trace Logging of REST Requests (#51684) (#52015)
Being able to trace log all REST requests to a node would make debugging
a number of issues a lot easier.

Add autoscaling API skelton (#51564)
The main purpose of this commit is to add a single autoscaling REST
endpoint skeleton, for the purpose of starting to build out the build
and testing infrastructure that will surround it. For example, rather
than commiting a fully-functioning autoscaling API, we introduce here
the skeleton so that we can start wiring up the build and testing
infrastructure, establish security roles/permissions, an so on. This
way, in a forthcoming PR that introduces actual functionality, that PR
will be smaller and have less distractions around that sort of
infrastructure.

If the configs are removed (by some horrific means), we should still allow tasks to be cleaned up easily.

Datafeeds and jobs with missing configs are now visible in their respective _stats calls and can be stopped/closed.

Always rewrite search shard request outside of the search thread pool (#51708) (#51979)
This change ensures that the rewrite of the shard request is executed in the network thread or in the refresh listener when waiting for an active shard. This allows queries that rewrite to match_no_docs to bypass the search thread pool entirely even if the can_match phase was skipped (pre_filter_shard_size > number of shards). Coordinating nodes don't have the ability to create empty responses so this change also ensures that at least one shard creates a full empty response while the other can return null ones. This is needed since creating true empty responses on shards require to create concrete aggregators which would be too costly to build on a network thread. We should move this functionality to aggregation builders in a follow up but that would be a much bigger change.
This change is also important for #49601 since we want to add the ability to use the result of other shards to rewrite the request of subsequent ones. For instance if the first M shards have their top N computed, the top worst document in the global queue can be pass to subsequent shards that can then rewrite to match_no_docs if they can guarantee that they don't have any document better than the provided one.

Tanguy Leroux d86a7ad6d2 Give more time to AutoFollowIT tests (#51938)
AutoFollowIT tests are regularly failing on CI because they rely 
on how cluster state updates are processed within the integration 
clusters. We tried to limit this in #49141 by moving to latches 
instead of waiting for assertions to pass but there are still some 
places were it still need to wait for the cluster state updates to 
be processed and auto-follow stats to be updated.

This commit gives more time to assertBusy() that verifies the 
AutoFollowStats (up to 60 seconds) and also always log the 
auto-follow stats in case the assertions failed.

Closes #48982

Create a class to hold field capabilities for one index. (#51844)
Currently, the same class `FieldCapabilities` is used both to represent the
capabilities for one index, and also the merged capabilities across indices. To
help clarify the logic, this PR proposes to create a separate class
`IndexFieldCapabilities` for the capabilities in one index. The refactor will
also help when adding `source_path` information in #49264, since the merged
source path field will have a different structure from the field for a single index.

Individual changes:
* Add a new class IndexFieldCapabilities.
* Remove extra constructor from FieldCapabilities.
* Combine the add and merge methods in FieldCapabilities.Builder.

David Roberts 9d55c45b5a [ML] Improve multiline_start_pattern for CSV in find_file_structure (#51737)
The work to switch file upload over to treating delimited files
like semi-structured text and using the ingest pipeline for CSV
parsing makes the multi-line start pattern used for delimited
files much more critical than it used to be.

Previously it was always based on the time field, even if that
was towards the end of the columns, and no multi-line pattern
was created if no timestamp was detected.

This change improves the multi-line start pattern by:

1. Never creating a multi-line pattern if the sample contained
   only single line records.  This improves the import
   efficiency in a common case.
2. Choosing the leftmost field that has a well-defined pattern,
   whether that be the time field or a boolean/numeric field.
   This reduces the risk of a field with newlines occurring
   earlier, and also means the algorithm doesn't automatically
   fail for data without a timestamp.

Reenable testWhenUserLimitedByOnlyAliasOfIndexCanWriteToIndexWhichWasRolledoverByILMPolicy (#51768) (#51801)
We suspect the flakiness could’ve come from the fact that the rollover
step used to create the new index and roll the write alias to the new
index in separate cluster state updates. So the assertion that the
rolled index exists could’ve passed in the test but, before the
alias was rolled over to the new index, the subsequent write we execute
in the test (namely
`indexDocs("test_user", "x-pack-test-password", "foo_alias", 1)`)
would’ve sent the new document to the source index (ie. foo-logs-000001)

This would see the source index containing 3 documents and the rolled
index (foo-logs-000002) 0 documents.

However, we fixed this and the rollover step executes the “create index
and roll alias” in one single cluster update, so this situation should
not occur anymore.

Fixes for the REST specification (#51791)
* REST: Test: Fix the `accept_enterprise` parameter for Get License API (#51527)

The Get License API specifies the `accept_enterprise` parameter as a `boolean`:

0ca5cb8cb6/x-pack/plugin/src/test/resources/rest-api-spec/api/license.get.json (L22-L27)

In the test, a `string` is passed however, which makes the test compilation fail in the Go client.

* Fix the "slices" parameter for the Delete By Query API in the REST specification (#51535)

This patch updates the `type` parameter in the Delete By Query API: according to
[the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-delete-by-query.html#docs-delete-by-query-slice),
it can be set to "auto", but the type in the documentation allows only numerical values.

This prevents people from setting the parameter to "auto" eg. in the Go client,
which generates source from the specification, and sets the corresponding Go
type as number.

The patch uses the `|` notation, which we have discussed previously for encoding
a "polymorphic" parameter like this.

[7.x][ML] Remove index.unassigned.node_left.delayed_timeout setting from M… (#51740) (#51764)
This setting was introduced with the purpose of reducing the time took by
tests that shut nodes down. Tests like `MlDistributedFailureIT` and
`NetworkDisruptionIT`. However, it is unfortunate to have to set the value
to an explicit value in production. In addition, and most important, the dynamically
choosing the value for this setting makes it impossible to adopt static index template configs
that we register via `IndexTemplateRegistry`, which we need to use in order to start
registering ILM policies for the ML indices.

This commit removes this setting from our templates. I run the tests a few times and could
not see execution time differing significantly.

[7.x] Stop policy on last PhaseCompleteStep instead of Termina… (#51758)
Currently when an ILM policy finishes its execution, the index moves into the `TerminalPolicyStep`,
denoted by a completed/completed/completed phase/action/step lifecycle execution state.

This commit changes the behavior so that the index lifecycle execution state halts at the last
configured phase's `PhaseCompleteStep`, so for instance, if an index were configured with a policy
containing a `hot` and `cold` phase, the index would stop at the `cold/complete/complete`
`PhaseCompleteStep`. This allows an ILM user to update the policy to add any later phases and have
indices configured to use that policy pick up execution at the newly added "later" phase. For
example, if a `delete` phase were added to the policy specified about, the index would then move
from `cold/complete/complete` into the `delete` phase.

The changes are to help users prepare for migration to next major

Warnings are added for when:
* A realm does not have an order config
* Multiple realms have the same order config

The warning messages are added to both deprecation API and loggings.
The main reasons for doing this are: 1) there is currently no automatic relay
between the two; 2) deprecation API is under basic and we need logging
for OSS.

SQL: Add optimisations for not-equalities (#51088) (#51700)
* Optimize not-equalities in con-/disjunctions

This commit adds optimisations of not-equalities in conjunctions and
disjunctions:
* for conjunctions, the not-equality can be optimized away when applied
together with a range or inequality, in case the not-equality point
falls outside the domain of the later condition; if its on the boarder,
it will modify the bound, to simply exclude the equality, if present;
otherwise no optimisation can be applied;
* for disjunctions, the not-equals could filter away the ranges and
inequalities, unless these include an equality on the bound, in which
case the entire condition becomes always true, but this would influence
the score() function, so it's been omitted;

* fix aggregations of inequalities in ranges

This commit fixes the loop that aggregates inequalities into ranges:
- it won't advance the outer loop index in case of a merge, since the
current element is removed;
- it will break the inner loop, since comparision against the element
selected in the outer loop can't continue, as it had been removed.

* Update the inflate byte limit to be the minimum of 10% the max heap, or 1GB (what it was previously)
* Stream data directly to the JSON parser, so if it is invalid, we don't have to inflate the whole stream to find out
* Throw when the maximum bytes are reach indicating that is why the request was rejected

Marios Trivyzas f373020349 SQL: Fix ORDER BY YEAR() function (#51562)
Previously, if YEAR() was used as and ORDER BY argument without being
wrapped with another scalar (e.g. YEAR(birth_date) + 10), no script
ordering was used but instead the underlying field (e.g. birth_date)
was used instead as a performance optimisation. This works correctly if
YEAR() is the only ORDER BY arg but if further args are used as tie
breakers for the ordering wrong results are produced. This is because
2 rows with the different birth_date but on the same year are not tied
as the underlying ordering is on birth_date and not on the
YEAR(birth_date), and the following ORDER BY args are ignored.

Remove this optimisation for YEAR() to avoid incorrect results in
such cases.

As a consequence another bug is revealed: scalar functions on top
of nested fields produce scripted sorting/filtering which is not yet
supported. In such cases no error was thrown but instead all values for
such nested fields were null and were passed to the script implementing
the sorting/filtering, producing incorrect results.

Detect such cases and throw a validation exception.

Always use one shard in vector REST tests. (#51643)
This PR tries to address the intermittent vector test failures on 7.x by making
sure we create indices with one shard.

The fix is based on this theory as to what's happening:
* On 7.x, the default number of shards is 1, but in REST tests we randomly use
2 in order to cover the multiple shards case. In the failing test run, we use 2
shards and all documents end up on only one shard.
* During a search, the response from the empty shard doesn't produce
deprecation warnings because  we never try to execute the script. If not all
shard responses contain the warning headers, then certain deprecation warnings
can be lost (due to the bug described in #33936).

Deprecate timeout.tcp_read AD/LDAP realm setting (#47305)
The timeout.tcp_read AD/LDAP realm setting, despite the low-level
allusion, controls the time interval the realms wait for a response for
a query (search or bind). If the connection to the server is synchronous
(un-pooled) the response timeout is analogous to the tcp read timeout.
But the tcp read timeout is irrelevant in the common case of a pooled
connection (when a Bind DN is specified).

The timeout.tcp_read qualifier is hereby deprecated in favor of
timeout.response.

In addition, the default value for both timeout.tcp_read and
timeout.response is that of timeout.ldap_search, instead of the 5s (but
the default for timeout.ldap_search is still 5s). The
timeout.ldap_search defines the server-controlled timeout of a search
request. There is no practical use case to have a smaller tcp_read
timeout compared to ldap_search (in this case the request would time-out
on the client but continue to be processed on the server). The proposed
change aims to simplify configuration so that the more common
configuration change, adjusting timeout.ldap_search up, has the expected
result (no timeout during searches) without any additional
modifications.

Check if interface is up for loopback devices only (#51583)
In the SQL with SSL tests, we need to find the interfaces that are up,
are loopback devices, or have a loopback address. If we check if the
device is up first, we can run into situations where the device is a
virtual ethernet device that might have disappeared between us seeing
the device, and checking if it is up. By first checking if the device is
a loopback device or it has a loopback address, then we can avoid
checking if the device is up except for loopback devices and therefore
we can avoid the disappearing virtual ethernet device problem.

Password-protected Keystore Feature Branch PR (#51123) (#51510)
* Reload secure settings with password (#43197)

If a password is not set, we assume an empty string to be
compatible with previous behavior.
Only allow the reload to be broadcast to other nodes if TLS is
enabled for the transport layer.

* Add passphrase support to elasticsearch-keystore (#38498)

This change adds support for keystore passphrases to all subcommands
of the elasticsearch-keystore cli tool and adds a subcommand for
changing the passphrase of an existing keystore.
The work to read the passphrase in Elasticsearch when
loading, which will be addressed in a different PR.

Subcommands of elasticsearch-keystore can handle (open and create)
passphrase protected keystores

When reading a keystore, a user is only prompted for a passphrase
only if the keystore is passphrase protected.

When creating a keystore, a user is allowed (default behavior) to create one with an
empty passphrase

Passphrase can be set to be empty when changing/setting it for an
existing keystore

Relates to: #32691
Supersedes: #37472

* Restore behavior for force parameter (#44847)

Turns out that the behavior of `-f` for the add and add-file sub
commands where it would also forcibly create the keystore if it
didn't exist, was by design - although undocumented.
This change restores that behavior auto-creating a keystore that
is not password protected if the force flag is used. The force
OptionSpec is moved to the BaseKeyStoreCommand as we will presumably
want to maintain the same behavior in any other command that takes
a force option.

*  Handle pwd protected keystores in all CLI tools  (#45289)

This change ensures that `elasticsearch-setup-passwords` and
`elasticsearch-saml-metadata` can handle a password protected
elasticsearch.keystore.
For setup passwords the user would be prompted to add the
elasticsearch keystore password upon running the tool. There is no
option to pass the password as a parameter as we assume the user is
present in order to enter the desired passwords for the built-in
users.
For saml-metadata, we prompt for the keystore password at all times
even though we'd only need to read something from the keystore when
there is a signing or encryption configuration.

* Modify docs for setup passwords and saml metadata cli (#45797)

Adds a sentence in the documentation of `elasticsearch-setup-passwords`
and `elasticsearch-saml-metadata` to describe that users would be
prompted for the keystore's password when running these CLI tools,
when the keystore is password protected.

* Elasticsearch keystore passphrase for startup scripts (#44775)

This commit allows a user to provide a keystore password on Elasticsearch
startup, but only prompts when the keystore exists and is encrypted.

The entrypoint in Java code is standard input. When the Bootstrap class is
checking for secure keystore settings, it checks whether or not the keystore
is encrypted. If so, we read one line from standard input and use this as the
password. For simplicity's sake, we allow a maximum passphrase length of 128
characters. (This is an arbitrary limit and could be increased or eliminated.
It is also enforced in the keystore tools, so that a user can't create a
password that's too long to enter at startup.)

In order to provide a password on standard input, we have to account for four
different ways of starting Elasticsearch: the bash startup script, the Windows
batch startup script, systemd startup, and docker startup. We use wrapper
scripts to reduce systemd and docker to the bash case: in both cases, a
wrapper script can read a passphrase from the filesystem and pass it to the
bash script.

In order to simplify testing the need for a passphrase, I have added a
has-passwd command to the keystore tool. This command can run silently, and
exit with status 0 when the keystore has a password. It exits with status 1 if
the keystore doesn't exist or exists and is unencrypted.

A good deal of the code-change in this commit has to do with refactoring
packaging tests to cleanly use the same tests for both the "archive" and the
"package" cases. This required not only moving tests around, but also adding
some convenience methods for an abstraction layer over distribution-specific
commands.

* Adjust docs for password protected keystore (#45054)

This commit adds relevant parts in the elasticsearch-keystore
sub-commands reference docs and in the reload secure settings API
doc.

* Fix failing Keystore Passphrase test for feature branch (#50154)

One problem with the passphrase-from-file tests, as written, is that
they would leave a SystemD environment variable set when they failed,
and this setting would cause elasticsearch startup to fail for other
tests as well. By using a try-finally, I hope that these tests will fail
more gracefully.

It appears that our Fedora and Ubuntu environments may be configured to
store journald information under /var rather than under /run, so that it
will persist between boots. Our destructive tests that read from the
journal need to account for this in order to avoid trying to limit the
output we check in tests.

* Run keystore management tests on docker distros (#50610)

* Add Docker handling to PackagingTestCase

Keystore tests need to be able to run in the Docker case. We can do this
by using a DockerShell instead of a plain Shell when Docker is running.

* Improve ES startup check for docker

Previously we were checking truncated output for the packaged JDK as
an indication that Elasticsearch had started. With new preliminary
password checks, we might get a false positive from ES keystore
commands, so we have to check specifically that the Elasticsearch
class from the Bootstrap package is what's running.

* Test password-protected keystore with Docker (#50803)

This commit adds two tests for the case where we mount a
password-protected keystore into a Docker container and provide a
password via a Docker environment variable.

We also fix a logging bug where we were logging the identifier for an
array of strings rather than the contents of that array.

* Add documentation for keystore startup prompting (#50821)

When a keystore is password-protected, Elasticsearch will prompt at
startup. This commit adds documentation for this prompt for the archive,
systemd, and Docker cases.

* Warn when unable to upgrade keystore on debian (#51011)

For Red Hat RPM upgrades, we warn if we can't upgrade the keystore. This
commit brings the same logic to the code for Debian packages. See the
posttrans file for gets executed for RPMs.

* Restore handling of string input

Adds tests that were mistakenly removed. One of these tests proved
we were not handling the the stdin (-x) option correctly when no
input was added. This commit restores the original approach of
reading stdin one char at a time until there is no more (-1, \r, \n)
instead of using readline() that might return null

* Apply spotless reformatting

* Use '--since' flag to get recent journal messages

When we get Elasticsearch logs from journald, we want to fetch only log
messages from the last run. There are two reasons for this. First, if
there are many logs, we might get a string that's too large for our
utility methods. Second, when we're looking for a specific message or
error, we almost certainly want to look only at messages from the last
execution.

Previously, we've been trying to do this by clearing out the physical
files under the journald process. But there seems to be some contention
over these directories: if journald writes a log file in between when
our deletion command deletes the file and when it deletes the log
directory, the deletion will fail.

It seems to me that we might be able to use journald's "--since" flag to
retrieve only log messages from the last run, and that this might be
less likely to fail due to race conditions in file deletion.

Unfortunately, it looks as if the "--since" flag has a granularity of
one-second. I've added a two-second sleep to make sure that there's a
sufficient gap between the test that will read from journald and the
test before it.

* Use new journald wrapper pattern

* Update version added in secure settings request

Disable diagnostic trust manager in tests (#51501)
This commit sets `xpack.security.ssl.diagnose.trust` to false in all
of our tests when running in FIPS 140 mode and when settings objects
are used to create an instance of the SSLService. This is needed
in 7.x because setting xpack.security.ssl.diagnose.trust to true
wraps SunJSSE TrustManager with our own DiagnosticTrustManager and
this is not allowed when SunJSSE is in FIPS mode.
An alternative would be to set xpack.security.fips.enabled to
true which would also implicitly disable
xpack.security.ssl.diagnose.trust but would have additional effects
(would require that we set PBKDF2 for password hashing algorithm in
all test clusters, would prohibit using JKS keystores in nodes even
if relevant tests have been muted in FIPS mode etc.)

This reverts commit d114c9db3e1d1a766f9f48f846eed0466125ce83.

David Roberts 3c223ceea1 [ML] Fix 2 digit year regex in find_file_structure (#51469)
The DATE and DATESTAMP Grok patterns match 2 digit years
as well as 4 digit years.  The pattern determination in
find_file_structure worked correctly in this case, but
the regex used to create a multi-line start pattern was
assuming a 4 digit year.  Also, the quick rule-out
patterns did not always correctly consider 2 digit years,
meaning that detection was inconsistent.

This change fixes both problems, and also extends the
tests for DATE and DATESTAMP to check both 2 and 4 digit
years.

[Transform] refactor naming leftovers and apply code formating (#51465) (#51470)
refactor renaming leftovers: "data frame transform" to "transforms", touch only internals (variable
names, non-public API's, doc strings, ...) and apply code-formatting (spotless). No logical changes.

Fix TimeSeriesLifecycleActionsIT.testShrinkAction (#51431) (#51467)
* Fix TimeSeriesLifecycleActionsIT.testShrinkAction

Shrinking a 6 shard index to 3 shards can be quite time consuming and
assertBusy probes the conditions at exponentially growing intervals.

This separates the one assertion that was used for all the conditions
into multiple assertBusy statements and increases the timeout for waiting
for the shrink to complete.

* Allow more time for shrink to complete

This commit allows more time for the shrink operation to complete in
testRetryFailedShrinkAction (separating the assertBusy calls too) and
testMoveToRolloverStep.

* Shrink to no more than 2 shards in tests
