With this commit we change the default behavior of
BulkProcessor from not backing off when getting
EsRejectedExecutionException to backing off exponentially.
This commit modifies the behavior after publication of a new cluster
state to only invoke the reroute logic once per batch of shard failures
rather than once per shard failure.
This commit modifies the internal representation of the JVM flag
UseCompressedOops to just be a String. This means we can just store the
value of the flag or "unknown" directly so that we do not have to engage
in shenanigans with three-valued logic around a boxed boolean.

With this commit we introduce limited retries with a backoff logic to BulkProcessor
when a bulk request has been rejeced with an EsRejectedExecutionException.
Fixes#14620.
Currently MetaDataMappingService parses the mapping updates, reserializes it and
finally calls MapperService.merge with the serialized mapping. Given that mapping
serialization only writes differences from the default, this is a bit unfair to
parsers since they can't know whether some option has been explicitly set or not.
Furthermore this can cause bugs with metadata fields given that these fields use
existing field types as defaults.
This commit changes MetaDataMappingService to call MapperService.merge with the
original mapping update.
This fixes the `lenient` parameter to be `missingClasses`. I will remove this boolean and we can handle them via the normal whitelist.
It also adds a check for sheisty classes (jar hell with the jdk).
This is inspired by the lucene "sheisty" classes check, but it has false positives. This check is more evil, it validates every class file against the extension classloader as a resource, to see if it exists there. If so: jar hell.
This jar hell is a problem for several reasons:
1. causes insanely-hard-to-debug problems (like bugs in forbidden-apis)
2. hides problems (like internal api access)
3. the code you think is executing, is not really executing
4. security permissions are not what you think they are
5. brings in unnecessary dependencies
6. its jar hell
The more difficult problems are stuff like jython, where these classes are simply 'uberjared' directly in, so you cant just fix them by removing a bogus dependency. And there is a legit reason for them to do that, they want to support java 1.4.
We currently randomly add a set of mock plugins to integ tests.
Sometimes it is necessary to omit this mock plugins, but other times you
may just want to suppress a particular mock plugin. For example, if you
have your own transport, you want to omit the asserting local transport
mock, since they would both try to set the transport.type.
This commit adds a callback for a cluster state task executor that will
be invoked if the execution of a batch of cluster state update tasks
led to a new cluster state and that new cluster state was successfully
published.
Closes#15482
This commit adds to JvmInfo the status of whether or not compressed
ordinary object pointers are enabled. Additionally, logging of the max
heap size and the status of the compressed ordinary object pointers flag
are provided on startup.

This commit addresses a few minor issues in the delimited payload token
filter docs:
- the provided example reversed the payloads associated with the
tokens "the" and "fox"
- two additional typos in the same sentence
- "per default" -> "by default"
- "default int to" -> "default into"
- adds two serial commas
