Adds support for scheduling commands to run at a later time on another
thread pool in the current thread's context:
```java
Runnable someCommand = () -> {System.err.println("Demo");};
someCommand = threadPool.getThreadContext().preserveContext(someCommand);
threadPool.schedule(timeValueMinutes(1), Names.GENERAL, someCommand);
```
This happens automatically for calls to `threadPool.execute` but `schedule`
and `scheduleWithFixedDelay` don't do that, presumably because scheduled
tasks are usually context-less. Rather than preserve the current context
on all scheduled tasks this just makes it possible to preserve it using
the syntax above.
To make this all go it moves the Runnables that wrap the commands from
EsThreadPoolExecutor into ThreadContext.
This, or something like it, is required to support reindex throttling.
Without this commit fetching the status of a reindex from a node that isn't
coordinating the reindex will fail. This commit properly registers reindex's
status so this doesn't happen. To do so it moves all task status registration
into NetworkModule and creates a method to register other statuses which the
reindex plugin calls.
When specifying more than one `filter` in a `constant_score`
query, the last one will be the only one that will be
executed, overwriting previous filters. It should rather
raise a ParseException to notify the user that only one
filter query is accepted.

Fix a potential parsing problem in GeoDistanceSortParser.
For an input like `{ [...], "coerce" = true, "ignore_malformed" = false }` the parser will
fail to parse the ignore_malformed boolean flag and will fall through to the last
else-branch where the boolean flag will be parsed as geo-hash and `ignore_malformed`
treated as field name.
This commit removes some dead code that resulted from removing the
ability for a field to have different names (after enforcing that fields
have the same full and index name).
Closes#17127
Test revealed a potential problem in the current GeoDistanceSortParser.
For an input like `{ [...], "coerce" = true, "ignore_malformed" = false }
the parser will fail to parse the `ignore_malformed` boolean flag and
will fall through to the last else-branch where the boolean flag will be
parsed as geo-hash and `ignore_malformed` treated as field name.
Adding fix and test that will fail with the old parser code.
Try to renew sync ID if `flush=true` on forceMerge
Today we do a force flush which wipes the sync ID if there is one which
can cause the lost of all benefits of the sync ID ie. fast recovery.
This commit adds a check to renew the sync ID if possible. The flush call
is now also not forced since the IW will show pending changes if the forceMerge added new segments.
if we keep using force we will wipe the sync ID even if no renew was actually needed.
Closes#17019
Adding methods and tests to ScriptSortBuilder that makes it implement NamedWritable and adds a fromXContent() method needed to read itseld from xContent. Also changing sortMode() setters in
FieldSortBuilder, GeoDistanceSortBuilder and ScriptSortBuilder to accept an enum instead of a String
value.

IndicesStore checks for `allocated elsewhere` for every shard not alocated on the local node
On each cluster-state update we check on the local node if we can delete some shards content.
For this we linearly walk all shards and check if they are allocated and started on another node
and if we can delete them locally. if we can delete them locally we go and ask other nodes if we can
delete them and then if the shared IS active elsewhere issue a state update task to delete it. Yet,
there is a bug in IndicesService#canDeleteShardContent which returns `true` even if that shards
datapath doesn't exist on the node which causes tons of unnecessary node to node communication and
as many state update task to be issued. This can have large impact on the cluster state processing
speed.
**NOTE:** This only happens for shards that have at least one shard allocated on the node ie. if an `IndexService` exists.

Add infrastructure to run REST tests on a multi-version cluster
This change adds the infrastructure to run the rest tests on a multi-node
cluster that users 2 different minor versions of elasticsearch. It doesn't implement
any dedicated BWC tests but rather leverages the existing REST tests.
Since we don't have a real version to test against, the tests uses the current version
until the first minor / RC is released to ensure the infrastructure works.
Given the amount of problems this change already found I think it's worth having this run with our test suite by default. The structure of this infra will likely change over time but for now it's a step into the right direction. We will likely want to split it up into integTests and integBwcTests etc. so each plugin can have it's own bwc tests but that's left for future refactoring.
After another round of input from @cbuescher this adds a few more sanity
checks to request parsing.
In addition adds (back) support for the reverse option.
