[ML] Get resources action should be lenient when sort field is unmapped (#42991) (#43046)
Get resources action sorts on the resource id. When there are no resources at
all, then it is possible the index does not contain a mapping for the resource
id field. In that case, the search api fails by default.

This commit adjusts the search request to ignore unmapped fields.

Alan Woodward 8e23e4518a Move construction of custom analyzers into AnalysisRegistry (#42940)
Both TransportAnalyzeAction and CategorizationAnalyzer have logic to build
custom analyzers for index-independent analysis. A lot of this code is duplicated,
and it requires the AnalysisRegistry to expose a number of internal provider
classes, as well as making some assumptions about when analysis components are
constructed.

This commit moves the build logic directly into AnalysisRegistry, reducing the
registry's API surface considerably.

Refactor put mapping request validation for reuse (#43005)
This commit refactors put mapping request validation for reuse. The

the same framework to indices aliases requests. This commit refactors
the put mapping request validation framework to allow for that.

Reindex max_docs parameter name (#42942)
Previously, a reindex request had two different size specifications in the body:
* Outer level, determining the maximum documents to process
* Inside the source element, determining the scroll/batch size.

The outer level size has now been renamed to max_docs to
avoid confusion and clarify its semantics, with backwards compatibility and
deprecation warnings for using size.
Similarly, the size parameter has been renamed to max_docs for
update/delete-by-query to keep the 3 interfaces consistent.

Finally, all 3 endpoints now support max_docs in both body and URL.

Remove `nonApplicationWrite` from `SSLDriver` (#42954)
Currently, when the SSLEngine needs to produce handshake or close data,
we must manually call the nonApplicationWrite method. However, this data
is only required when something triggers the need (starting handshake,
reading from the wire, initiating close, etc). As we have a dedicated
outbound buffer, this data can be produced automatically. Additionally,
with this refactoring, we combine handshake and application mode into a
single mode. This is necessary as there are non-application messages that
are sent post handshake in TLS 1.3. Finally, this commit modifies the
SSLDriver tests to test against TLS 1.3.

David Roberts 40c827a3b8 [ML] Close sample stream in find_file_structure endpoint (#42896)
A static code analysis revealed that we are not closing
the input stream in the find_file_structure endpoint.
This actually makes no difference in practice, as the
particular InputStream implementation in this case is
org.elasticsearch.common.bytes.BytesReferenceStreamInput
and its close() method is a no-op.  However, it is good
practice to close the stream anyway.

There is no pipeline check (present on 6.8) as it is impossible to verify when the pipeline was created, and therefore to make sure the format is depracated or not

David Roberts d5baedb789 [ML] Change dots in CSV column names to underscores (#42839)
Dots in the column names cause an error in the ingest
pipeline, as dots are special characters in ingest pipeline.
This PR changes dots into underscores in CSV field names
suggested by the ML find_file_structure endpoint _unless_
the field names are specifically overridden.  The reason for
allowing them in overrides is that fields that are not
mentioned in the ingest pipeline can contain dots.  But it's
more consistent that the default behaviour is to replace
them all.

Fix version parsing in various tests (#42871)
This commit fixes the version parsing in various tests. The issue here is that
the parsing was relying on java.version. However, java.version can contain
additional characters such as -ea for early access builds. See JEP 233:

Name                            Syntax
------------------------------  --------------
java.version                    $VNUM(\-$PRE)?
java.runtime.version            $VSTR
java.vm.version                 $VSTR
java.specification.version      $VNUM
java.vm.specification.version   $VNUM

Instead, we want java.specification.version.

Don't require TLS for single node clusters (#42830)
This commit removes the TLS cluster join validator.

This validator existed to prevent v6.x nodes (which mandated
TLS) from joining an existing cluster of v5.x nodes (which did
not mandate TLS) unless the 6.x node (and by implication the
5.x nodes) was configured to use TLS.

Since 7.x nodes cannot talk to 5.x nodes, this validator is no longer
needed.

Removing the validator solves a problem where single node clusters
that were bound to local interfaces were incorrectly requiring TLS
when they recovered cluster state and joined their own cluster.

David Roberts b61202b0a8 [ML] Add a limit on line merging in find_file_structure (#42501)
When analysing a semi-structured text file the
find_file_structure endpoint merges lines to form
multi-line messages using the assumption that the
first line in each message contains the timestamp.
However, if the timestamp is misdetected then this
can lead to excessive numbers of lines being merged
to form massive messages.

This commit adds a line_merge_size_limit setting
(default 10000 characters) that halts the analysis
if a message bigger than this is created.  This
prevents significant CPU time being spent subsequently
trying to determine the internal structure of the
huge bogus messages.

This change helps to prevent the situation where a binary
file uploaded to the find_file_structure endpoint is
detected as being text in the UTF-16 character set, and
then causes a large amount of CPU to be spent analysing

The approach is to check the distribution of zero bytes
between odd and even file positions, on the grounds that
UTF-16BE or UTF16-LE would have a very skewed distribution.

Remove Log4j 1.2 API as a dependency (#42702)
We had this as a dependency for legacy dependencies that still needed
the Log4j 1.2 API. This appears to no longer be necessary, so this
commit removes this artifact as a dependency.

To remove this dependency, we had to fix a few places where we were
accidentally relying on Log4j 1.2 instead of Log4j 2 (easy to do, since
both APIs were on the compile-time classpath).

Finally, we can remove our custom Netty logger factory. This was needed
when we were on Log4j 1.2 and handled logging in our own unique
way. When we migrated to Log4j 2 we could have dropped this
dependency. However, even then Netty would still pick up Log4j 1.2 since
it was on the classpath, thus the advantage to removing this as a
dependency now.

Ioannis Kakavas 7cabe8acc9 Fix refresh remote JWKS logic (#42662)
This change ensures that:

- We only attempt to refresh the remote JWKS when there is a
signature related error only ( BadJWSException instead of the
geric BadJOSEException )
- We do call OpenIDConnectAuthenticator#getUserClaims upon
successful refresh.
- We test this in OpenIdConnectAuthenticatorTests.

Without this fix, when using the OpenID Connect realm with a remote
JWKSet configured in `op.jwks_path`, the refresh would be triggered
for most configuration errors ( i.e. wrong value for `op.issuer` )
and the kibana wouldn't get a response and timeout since
`getUserClaims` wouldn't be called because
`ReloadableJWKSource#reloadAsync` wouldn't call `onResponse` on the
future.

Ioannis Kakavas 24a794fd6b Fix testTokenExpiry flaky test (#42585)
Test was using ClockMock#rewind passing the amount of nanoseconds
in order to "strip" nanos from the time value. This was intentional
as the expiration time of the UserToken doesn't have nanosecond
precision.
However, ClockMock#rewind doesn't support nanos either, so when it's
called with a TimeValue, it rewinds the clock by the TimeValue's
millis instead. This was causing the clock to go enough millis
before token expiration time and the test was passing. Once every
few hundred times though, the TimeValue by which we attempted to
rewind the clock only had nanos and no millis, so rewind moved the
clock back just a few millis, but still after expiration time.

This change moves the clock explicitly to the same instant as expiration,
using clock.setTime and disregarding nanos.

Tanguy Leroux 6bec876682 Improve Close Index Response (#39687)
This changes the `CloseIndexResponse` so that it reports closing result
for each index. Shard failures or exception are also reported per index,
and the global acknowledgment flag is computed from the index results
only.

The response looks like:
```
{
  "acknowledged" : true,
  "shards_acknowledged" : true,
  "indices" : {
    "docs" : {
      "closed" : true
    }
  }
}
```

The response reports shard failures like:
```
{
  "acknowledged" : false,
  "shards_acknowledged" : false,
  "indices" : {
    "docs-1" : {
      "closed" : true
    },
    "docs-2" : {
      "closed" : false,
      "shards" : {
        "1" : {
          "failures" : [
            {
              "shard" : 1,
              "index" : "docs-2",
              "status" : "BAD_REQUEST",
              "reason" : {
                "type" : "index_closed_exception",
                "reason" : "closed",
                "index_uuid" : "JFmQwr_aSPiZbkAH_KEF7A",
                "index" : "docs-2"
              }
            }
          ]
        }
      }
    },
    "docs-3" : {

    }
  }
}
```

David Roberts 34de68b007 [ML] Fix possible race condition when closing an opening job (#42506)
This change fixes a race condition that would result in an
in-memory data structure becoming out-of-sync with persistent
tasks in cluster state.

If repeated often enough this could result in it being
impossible to open any ML jobs on the affected node, as the
master node would think the node had capacity to open another
job but the chosen node would error during the open sequence
due to its in-memory data structure being full.

The race could be triggered by opening a job and then closing
it a tiny fraction of a second later.  It is unlikely a user
of the UI could open and close the job that fast, but a script
or program calling the REST API could.

The nasty thing is, from the externally observable states and
stats everything would appear to be fine - the fast open then
close sequence would appear to leave the job in the closed
state.  It's only later that the leftovers in the in-memory
data structure might build up and cause a problem.

David Roberts f472186b9f [ML] Improve file structure finder timestamp format determination (#41948)
This change contains a major refactoring of the timestamp
format determination code used by the ML find file structure
endpoint.

Previously timestamp format determination was done separately
for each piece of text supplied to the timestamp format finder.
This had the drawback that it was not possible to distinguish
dd/MM and MM/dd in the case where both numbers were 12 or less.
In order to do this sensibly it is best to look across all the
available timestamps and see if one of the numbers is greater
than 12 in any of them.  This necessitates making the timestamp
format finder an instantiable class that can accumulate evidence
over time.

Another problem with the previous approach was that it was only
possible to override the timestamp format to one of a limited
set of timestamp formats.  There was no way out if a file to be
analysed had a timestamp that was sane yet not in the supported
set.  This is now changed to allow any timestamp format that can
be parsed by a combination of these Java date/time formats:
yy, yyyy, M, MM, MMM, MMMM, d, dd, EEE, EEEE, H, HH, h, mm, ss,
a, XX, XXX, zzz
Additionally S letter groups (fractional seconds) are supported
providing they occur after ss and separated from the ss by a dot,
comma or colon.  Spacing and punctuation is also permitted with
the exception of the question mark, newline and carriage return
characters, together with literal text enclosed in single quotes.

The full list of changes/improvements in this refactor is:

- Make TimestampFormatFinder an instantiable class
- Overrides must be specified in Java date/time format - Joda
  format is no longer accepted
- Joda timestamp formats in outputs are now derived from the
  determined or overridden Java timestamp formats, not stored
  separately
- Functionality for determining the "best" timestamp format in
  a set of lines has been moved from TextLogFileStructureFinder
  to TimestampFormatFinder, taking advantage of the fact that
  TimestampFormatFinder is now an instantiable class with state
- The functionality to quickly rule out some possible Grok
  patterns when looking for timestamp formats has been changed
  from using simple regular expressions to the much faster
  approach of using the Shift-And method of sub-string search,
  but using an "alphabet" consisting of just 1 (representing any
  digit) and 0 (representing non-digits)
- Timestamp format overrides are now much more flexible
- Timestamp format overrides that do not correspond to a built-in
  Grok pattern are mapped to a %{CUSTOM_TIMESTAMP} Grok pattern
  whose definition is included within the date processor in the
  ingest pipeline
- Grok patterns that correspond to multiple Java date/time
  patterns are now handled better - the Grok pattern is accepted
  as matching broadly, and the required set of Java date/time
  patterns is built up considering all observed samples
- As a result of the more flexible acceptance of Grok patterns,
  when looking for the "best" timestamp in a set of lines
  timestamps are considered different if they are preceded by
  a different sequence of punctuation characters (to prevent
  timestamps far into some lines being considered similar to
  timestamps near the beginning of other lines)
- Out-of-the-box Grok patterns that are considered now include
  %{DATE} and %{DATESTAMP}, which have indeterminate day/month
  ordering
- The order of day/month in formats with indeterminate day/month
  order is determined by considering all observed samples (plus
  the server locale if the observed samples still do not suggest
  an ordering)

Fix settings prefix for realm truststore password (#42413)
As part of #30241 realm settings were changed to be true affix
settings. In the process of this change, the "ssl." prefix was lost
from the realm truststore password. It should be:

    xpack.security.authc.realms.<type>.<name>.ssl.truststore.password

Due to a mismatch between the way we define SSL settings and  load SSL
contexts, there was no way to define this legacy password setting in a
realm config.

The settings validation would reject "ssl.truststore.password" but the
SSL service would ignore "truststore.password"

Simon Willnauer a79cd77e5c Remove IndexShard dependency from Repository (#42213)
* Remove IndexShard dependency from Repository

In order to simplify repository testing especially for BlobStoreRepository
it's important to remove the dependency on IndexShard and reduce it to
Store and MapperService (in the snapshot case). This significantly reduces
the dependcy footprint for Repository and allows unittesting without starting
nodes or instantiate entire shard instances. This change deprecates the old
method signatures and adds a unittest for FileRepository to show the advantage
of this change.
In addition, the unittesting surfaced a bug where the internal file names that
are private to the repository were used in the recovery stats instead of the
target file names which makes it impossible to relate to the actual lucene files
in the recovery stats.

However if the delay is smaller or if it's not a multiple of the rollup interval
the job can create incomplete buckets because the max boundary for a job is computed

fixes this computation by applying the delay substraction before the rounding in order to ensure
that we never create a boundary that falls in a middle of a bucket.

[7.x Backport] Force selection of calendar or fixed intervals (#41906)
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.

This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed.  And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit).  This arrangement is very
error-prone for users.

This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.

The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.

The change applies to both REST and java clients.

Hash token values for storage (#41792) (#42220)
This commit changes how access tokens and refresh tokens are stored
in the tokens index.

Access token values are now hashed before being stored in the id
field of the `user_token` and before becoming part of the token
document id. Refresh token values are hashed before being stored
in the token field of the `refresh_token`. The tokens are hashed
without a salt value since these are v4 UUID values that have
enough entropy themselves. Both rainbow table attacks and offline
brute force attacks are impractical.

As a side effect of this change and in order to support multiple
concurrent refreshes as introduced in #39631, upon refreshing an
<access token, refresh token> pair, the superseding access token
and refresh tokens values are stored in the superseded token doc,
encrypted with a key that is derived from the superseded refresh
token. As such, subsequent requests to refresh the same token in
the predefined time window will return the same superseding access
token and refresh token values, without hitting the tokens index
(as this only stores hashes of the token values). AES in GCM
mode is used for encrypting the token values and the key
derivation from the superseded refresh token uses a small number
of iterations as it needs to be quick.

For backwards compatibility reasons, the new behavior is only
enabled when all nodes in a cluster are in the required version
so that old nodes can cope with the token values in a mixed
cluster during a rolling upgrade.

Update ciphers for TLSv1.3 and JDK11 if available (#42082)
This commit updates the default ciphers and TLS protocols that are used
when the runtime JDK supports them. New cipher support has been
introduced in JDK 11 and 12 along with performance fixes for AES GCM.
The ciphers are ordered with PFS ciphers being most preferred, then
AEAD ciphers, and finally those with mainstream hardware support. When
available stronger encryption is preferred for a given cipher.

This is a backport of #41385 and #41808. There are known JDK bugs with
TLSv1.3 that have been fixed in various versions. These are:

1. The JDK's bundled HttpsServer will endless loop under JDK11 and JDK
12.0 (Fixed in 12.0.1) based on the way the Apache HttpClient performs
a close (half close).
2. In all versions of JDK 11 and 12, the HttpsServer will endless loop
when certificates are not trusted or another handshake error occurs. An
email has been sent to the openjdk security-dev list and #38646 is open
to track this.
3. In JDK 11.0.2 and prior there is a race condition with session
resumption that leads to handshake errors when multiple concurrent
handshakes are going on between the same client and server. This bug
does not appear when client authentication is in use. This is
JDK-8213202, which was fixed in 11.0.3 and 12.0.
4. In JDK 11.0.2 and prior there is a bug where resumed TLS sessions do
not retain peer certificate information. This is JDK-8212885.

The way these issues are addressed is that the current java version is
checked and used to determine the supported protocols for tests that
provoke these issues.

Improve the hard_limit memory audit message by reporting how many bytes
over the configured memory limit the job was at the point of the last
allocation failure.

Previously the model memory usage was reported, however this was
inaccurate and hence of limited use -  primarily because the total
memory used by the model can decrease significantly after the models
status is changed to hard_limit but before the model size stats are
reported from autodetect to ES.

While this PR contains the changes to the format of the hard_limit audit
message it is dependent on modifications to the ml-cpp backend to
send additional data fields in the model size stats message. These
changes will follow in a subsequent PR. It is worth noting that this PR
must be merged prior to the ml-cpp one, to keep CI tests happy.

Igor Motov 076ca75ea5 SQL: Suppress geo tests failing on tr-TR locale (#42200)
Due to a bug in JTS WKT parser, JTS cannot parse most of WKT shapes if
the shape type is written in the lower case. For examples `point (1 2)`
is causing JTS inside H2GIS to fail on tr-TR locale as a result  of 
case-insensitive comparison.

Ryan Ernst fa1d1d1f57 Deprecate the native realm migration tool (#42142)
The migrate tool was added when the native realm was created, to aid
users in converting from file realms that were per node, into the
cluster managed native realm. While this tool was useful at the time,
users should now be using the native realm directly. This commit
deprecates the tool, to be removed in a followup for 8.0.

SQL: Fix issue regarding INTERVAL * number (#42014)
Interval * integer number is a valid operation which previously was
only supported for foldables (literals) and not when a field was
involved. That was because:

1. There was no common type returned for that combination
2. The `BinaryArithmeticOperation` was permitting the multiplication
(called by fold()) but the BinaryArithmeticProcessor didn't allow it

Moreover the error message for invalid arithmetic operations was wrong
because of the issue with the overloading methods of
`LoggerMessageFormat.format`.

Enforce transport TLS on Basic with Security (#42150)
If a basic license enables security, then we should also enforce TLS
on the transport interface.

This was already the case for Standard/Gold/Platinum licenses.

For Basic, security defaults to disabled, so some of the process
around checking whether security is actuallY enabled is more complex
now that we need to account for basic licenses.

SQL: Add initial geo support (#42031) (#42135)
Adds an initial limited implementations of geo features to SQL. This implementation is based on the [OpenGIS® Implementation Standard for Geographic information - Simple feature access](http://www.opengeospatial.org/standards/sfs), which is the current standard for GIS system implementation. This effort is concentrate on SQL option AKA ISO 19125-2. 

Queries that are supported as a result of this initial implementation

Metadata commands

- `DESCRIBE table`  - returns the correct column types `GEOMETRY` for geo shapes and geo points.
- `SHOW FUNCTIONS` - returns a list that includes supported `ST_` functions
- `SYS TYPES` and `SYS COLUMNS` display correct types `GEO_SHAPE` and `GEO_POINT` for geo shapes and geo points accordingly. 

Returning geoshapes and geopoints from elasticsearch

- `SELECT geom FROM table` - returns the geoshapes and geo_points as libs/geo objects in JDBC or as WKT strings in console.
- `SELECT ST_AsWKT(geom) FROM table;` and `SELECT ST_AsText(geom) FROM table;`- returns the geoshapes ang geopoints in their WKT representation;

Using geopoints to elasticsearch

- The following functions will be supported for geopoints in queries, sorting and aggregations: `ST_GeomFromText`, `ST_X`, `ST_Y`, `ST_Z`, `ST_GeometryType`, and `ST_Distance`. In most cases when used in queries, sorting and aggregations, these function are translated into script. These functions can be used in the SELECT clause for both geopoints and geoshapes. 
- `SELECT * FROM table WHERE ST_Distance(ST_GeomFromText(POINT(1 2), point) < 10;` - returns all records for which `point` is located within 10m from the `POINT(1 2)`. In this case the WHERE clause is translated into a range query.

Limitations:

Geoshapes cannot be used in queries, sorting and aggregations as part of this initial effort. In order to fully take advantage of geoshapes we would need to have access to geoshape doc values, which is coming in #37206. `ST_Z` cannot be used on geopoints in queries, sorting and aggregations since we don't store altitude in geo_point doc values.

SQL: Remove CircuitBreaker from parser (#41835)
The CircuitBreaker was introduced as means of preventing a
`StackOverflowException` during the build of the AST by the parser.

The ANTLR4 grammar causes a weird behaviour for a Parser Listener.
The `enterEveryRule()` method is often called with a different parsing
context than the respective `exitEveryRule()`. This makes it difficult
to keep track of the tree's depth, and a custom Map was used as an
attempt of matching the contextes as they are encounter during `enter`
and during `exit` of the rules.

This approach had 2 important drawbacks:
1. It's hard to maintain this custom Map as the grammar changes.
2. The CircuitBreaker could often lead to false positives which caused
valid queries to return an Exception and prevent them from executing.

So, this removes completely the CircuitBreaker which is replaced be
a simple handling of the `StackOverflowException`

Log warning when unlicensed realms are skipped (#41828)
Because realms are configured at node startup, but license levels can
change dynamically, it is possible to have a running node that has a
particular realm type configured, but that realm is not permitted under
the current license.
In this case the realm is silently ignored during authentication.

This commit adds a warning in the elasticsearch logs if authentication
fails, and there are realms that have been skipped due to licensing.
This message is not intended to imply that the realms could (or would)
have successfully authenticated the user, but they may help reduce
confusion about why authentication failed if the caller was expecting
the authentication to be handled by a particular realm that is in fact
unlicensed.

Simplify filtering addresses on interfaces (#41758)
This commit is a refactoring of how we filter addresses on
interfaces. In particular, we refactor all of these methods into a
common private method. We also change the order of logic to first check
if an address matches our filter and then check if the interface is
up. This is to possibly avoid problems we are seeing where devices are
flapping up and down while we are checking for loopback addresses. We do
not expect the loopback device to flap up and down so by reversing the
logic here we avoid that problem on CI machines. Finally, we expand the
error message when this does occur so that we know which device is
flapping.

Security Tokens moved to a new separate index (#40742)
This commit introduces the `.security-tokens` and `.security-tokens-7`
alias-index pair. Because index snapshotting is at the index level granularity
(ie you cannot snapshot a subset of an index) snapshoting .`security` had
the undesirable effect of storing ephemeral security tokens. The changes
herein address this issue by moving tokens "seamlessly" (without user
intervention) to another index, so that a "Security Backup" (ie snapshot of
`.security`) would not be bloated by ephemeral data.

Drop distinction in entries for keystore (#41701)
Today we allow adding entries from a file or from a string, yet we
internally maintain this distinction such that if you try to add a value
from a file for a setting that expects a string or add a value from a
string for a setting that expects a file, you will have a bad time. This
causes a pain for operators such that for each setting they need to know
this difference. Yet, we do not need to maintain this distinction
internally as they are bytes after all. This commit removes that
distinction and includes logic to upgrade legacy keystores.

This commit removes the usage of the `BulkProcessor` to write history documents
and delete triggered watches on a `EsRejectedExecutionException`. Since the
exception could be handled on the write thread, the write thread can be blocked
waiting on watcher threads (due to a synchronous method). This is problematic
since those watcher threads can be blocked waiting on write threads.

This commit also moves the handling of the exception to the generic threadpool
to avoid submitting write requests from the write thread pool.

Nhat Nguyen 887f3f2c83 Simplify initialization of max_seq_no of updates (#41161)
Today we choose to initialize max_seq_no_of_updates on primaries only so
we can deal with a situation where a primary is on an old node (before
6.5) which does not have MUS while replicas on new nodes (6.5+).
However, this strategy is quite complex and can lead to bugs (for
example #40249) since we have to assign a correct value (not too low) to
MSU in all possible situations (before recovering from translog,
restoring history on promotion, and handing off relocation).

Fortunately, we don't have to deal with this BWC in 7.0+ since all nodes
in the cluster should have MSU. This change simplifies the
initialization of MSU by always assigning it a correct value in the
constructor of Engine regardless of whether it's a replica or primary.

Remove dedicated SSL network write buffer (#41654)
This is related to #27260. Currently for the SSLDriver we allocate a
dedicated network write buffer and encrypt the data into that buffer one
buffer at a time. This requires constantly switching between encrypting
and flushing. This commit adds a dedicated outbound buffer for SSL
operations that will internally allocate new packet sized buffers as
they are need (for writing encrypted data). This allows us to totally
encrypt an operation before writing it to the network. Eventually it can
be hooked up to buffer recycling.

This commit also backports the following commit:

Handle WRAP ops during SSL read

It is possible that a WRAP operation can occur while decrypting
handshake data in TLS 1.3. The SSLDriver does not currently handle this
well as it does not have access to the outbound buffer during read call.
This commit moves the buffer into the Driver to fix this issue. Data
wrapped during a read call will be queued for writing after the read
call is complete.

Async Snapshot Repository Deletes (#40144) (#41571)
Motivated by slow snapshot deletes reported in e.g. #39656 and the fact that these likely are a contributing factor to repositories accumulating stale files over time when deletes fail to finish in time and are interrupted before they can complete.

* Makes snapshot deletion async and parallelizes some steps of the delete process that can be safely run concurrently via the snapshot thread poll
   * I did not take the biggest potential speedup step here and parallelize the shard file deletion because that's probably better handled by moving to bulk deletes where possible (and can still be parallelized via the snapshot pool where it isn't). Also, I wanted to keep the size of the PR manageable.
* See https://github.com/elastic/elasticsearch/pull/39656#issuecomment-470492106
* Also, as a side effect this gives the `SnapshotResiliencyTests` a little more coverage for master failover scenarios (since parallel access to a blob store repository during deletes is now possible since a delete isn't a single task anymore).
* By adding a `ThreadPool` reference to the repository this also lays the groundwork to parallelizing shard snapshot uploads to improve the situation reported in #39657

Costin Leau b288b88ba0 SQL: Use field caps inside DESCRIBE TABLE as well (#41377)
Thanks to #34071, there is enough information in field caps to infer
the table structure and thus use the same API consistently across the
IndexResolver.

Remove dedicated SSL network write buffer (#41283)
This is related to #27260. Currently for the SSLDriver we allocate a
dedicated network write buffer and encrypt the data into that buffer one
buffer at a time. This requires constantly switching between encrypting
and flushing. This commit adds a dedicated outbound buffer for SSL
operations that will internally allocate new packet sized buffers as
they are need (for writing encrypted data). This allows us to totally
encrypt an operation before writing it to the network. Eventually it can
be hooked up to buffer recycling.

SSLDriver can transition to CLOSED in handshake (#41458)
TLS 1.3 changes to the SSLEngine introduced a scenario where a UNWRAP
call during a handshake can consume a close notify alerty without
throwing an exception. This means that we continue down a codepath where
we assert that we are still in handshaking mode. Transitioning to closed
from handshaking is a valid scenario. This commit removes this
assertion.

Handle unmapped fields in _field_caps API (#34071) (#41426)
Today the `_field_caps` API returns the list of indices where a field
is present only if this field has different types within the requested indices.
However if the request is an index pattern (or an alias, or both...) there
is no way to infer the indices if the response contains only fields that have
the same type in all indices. This commit changes the response to always return
the list of indices in the response. It also adds a way to retrieve unmapped field
in a specific section per field called `unmapped`. This section is created for each field
that is present in some indices but not all if the parameter `include_unmapped` is set to
true in the request (defaults to false).

Albert Zaharovits fe5789ada1 Fix Has Privilege API check on restricted indices (#41226)
The Has Privileges API allows to tap into the authorization process, to validate
privileges without actually running the operations to be authorized. This commit
fixes a bug, in which the Has Privilege API returned spurious results when checking
for index privileges over restricted indices (currently .security, .security-6,
.security-7). The actual authorization process is not affected by the bug.

Also refactored to use a ConstructingObjectParser and removed the
private ctor and setter for sources, making it mandatory.

Implement the ANSI SQL CASE expression which provides the if/else
functionality common to most programming languages.

The CASE expression can have multiple WHEN branches and becomes a
powerful tool for SQL queries as it can be used in SELECT, WHERE,
GROUP BY, HAVING and ORDER BY clauses.

Fix role mapping DN field wildcards for users with NULL DNs (#41343)
The `DistinguishedNamePredicate`, used for matching users to role mapping
expressions, should handle users with null DNs. But it fails to do so (and this is
a NPE bug), if the role mapping expression contains a lucene regexp or a wildcard.

The fix simplifies `DistinguishedNamePredicate` to not handle null DNs at all, and
instead use the `ExpressionModel#NULL_PREDICATE` for the DN field, just like
any other missing user field.
