Currently both ProfileResult and CollectorResult print the time field in a human readable string format
(e.g. "time": "55.20315000ms"). When trying to parse this back to a long value, for example to use in
the planned high level java rest client, we can lose precision because of conversion and rounding issues.
This change adds a new additional field (`time_in_nanos`) to the profile response to be able to get the
original time value in nanoseconds back.
The old `time` field is only printed when the `?`human=true` flag in the url is set. This follow the behaviour for
all other stats-related apis. Also the format of the `time` field is slightly changed. Instead of always formatting
the output as a 10-digit ms value, by using the `XContentBuilder#timeValueField()` method we now print
the largest time unit present is used (e.g. "s", "ms", "micros").
An operation that completed successfully on a primary can result in a
version conflict on a replica due to the asynchronous nature of
operations. When a replica operation results in a version conflict, the
operation is not added to the translog. This leads to gaps in the
translog which is problematic as it can lead to situations where a
replica shard can never advance its local checkpoint. As such operations
are just normal course of business for a replica shard, these operations
should be treated as if they completed successfully. This commit adds
these operations to the translog.

For certain situations, end-users need the base path for Elasticsearch
logs. Exposing this as a property is better than hard-coding the path
into the logging configuration file as otherwise the logging
configuration file could easily diverge from the Elasticsearch
configuration file. Additionally, Elasticsearch will only have
permissions to write to the log directory configured in the
Elasticsearch configuration file. This commit adds a property that
exposes this base path.
One use-case for this is configuring a rollover strategy to retain logs
for a certain period of time. As such, we add an example of this to the
documentation.
Additionally, we expose the property es.logs.cluster_name as this is
used as the name of the log files in the default configuration.
Finally, we expose es.logs.node_name in cases where node.name is
explicitly set in case users want to include the node name as part of
the name of the log files.

When logger.level is set, we end up configuring a logger named "level"
because we look for all settings of the form "logger\..+" as configuring
a logger. Yet, logger.level is special and is meant to only configure
the default logging level. This commit causes is to avoid not
configuring a logger named level.

The IndexingOperationListener interface did not provide any
information about the shard id when a document was indexed.
This commit adds the shard id as the first parameter to all methods
in the IndexingOperationListener.
This commit is a simple cleanup of the code related to cgroup stats:
- reduce visibility of a method
- remove an unneeded logger guard
- cleanup the formatting of comments
TransportInterceptors are commonly used to enrich requests with headers etc.
which requires access the the thread context. This is not always easily possible
since threadpools are hard to access for instance if the interceptor is used on a transport client.
This commit passes on the thread context to all the interceptors for further consumption.
Closes#22585
Deleting indices is an important event in a cluster and as such should
be logged at the info level. This commit changes the logging level on
index deletion to the info level.

This commit removes a logging test that is now obsolete. This test was
added when we included a forked version of some Log4j 2 classes to
workaround a bug in Log4j 2. This bug was fixed and a version of Log4j 2
incorporating this fix was previously integrated into Elaticsearch. At
that time, the forked versions were removed, and this test should have
been removed with it.
We have made the security manager non-optional, but the Javadocs for
Security.java imply that it still is. This commit fixes this issue.

This is related to #22116. netty channels require socket `connect` and
`accept` privileges. Netty does not currently wrap these operations
with `doPrivileged` blocks. These changes extend the netty channels
and wrap calls to the relevant super methods in doPrivileged blocks.
ClusterService and TransportService expect the local discovery node to be set
before they are started but this requires manual interaction and is error prone since
to work absolutely correct they should share the same instance (same ephemeral ID).
TransportService also has 2 modes of operation, mainly realted to transport client vs. internal
to a node. This change removes the mode where we don't maintain a local node and uses a dummy local
node in the transport client since we don't bind to any port in such a case.
Local discovery node instances are now managed by the node itself and only suppliers and factories that allow
creation only once are passed to TransportService and ClusterService.
There was still small race in MockTcpTransport where channesl that are concurrently
closing are not yet removed from the reference tracking causing tests to fail. Compared to
the other races before this is a rather small windown and requires very very short test durations.

Today there are several races / holes in TcpTransport and MockTcpTransport
that can allow connections to be opened and remain unclosed while the actual
transport implementation is closed. A recently added assertions in #22554 exposes
these problems. This commit fixes several issues related to missed locks or channel
creations outside of a lock not checking if the resource is still open.
