Today when we load the Netty plugins, we indirectly cause several Netty
classes to initialize. This is because we attempt to load some classes
by name, and loading these classes is done in a way that triggers a long
chain of class initializers within Netty. We should not do this, this
can lead to log messages before the logger is loader, and it leads to
initialization in cases when the classes would never be needed (for
example, Netty 3 class initialization is never needed if Netty 4 is
used, and vice versa). This commit avoids this early initialization of
these classes by removing the need for the early loading.

The method requires pairs of fieldnames and property arguments and will fail if
the varargs input is an uneven number. We should check this and fail with an
appropriate IllegalArgumentException instead.

Elasticsearch doesn't have any automatic mechanism to share these
components between indexes. If any component is heavy enough to
warrant such sharing then it is the Pugin's responsibility to do
it in their {@link AnalysisProvider} implementation. We recommend
against doing this unless absolutely necessary because it can be
difficult to get the caching right given things like behavior
changes across versions.

This commit cleans up indices in a snapshot repository when all
snapshots containing the index are all deleted. Previously, empty
indices folders would lay around after all snapshots containing
them were deleted.
This commit updates Jackson to the 2.8.1 version, which is more strict when it comes to build objects. It also adds the snakeyaml dependency that was previously shaded in jackson libs.
It also closes#18076
Instead of being lenient in QueryParseContext#parseInnerQueryBuilder we check that the token where the parser stopped reading was END_OBJECT, and throw error otherwise. This is a best effort to verify that the parsers read a whole object rather than stepping out in the middle of it due to malformed queries.
Fuzzy Query, like many other queries, used to parse even when the query referred to multiple fields and the first one would win. We rather throw an exception now instead.
Also added test for short prefix query variant and modified the parsing code to consume the whole query object.

Closes#19547
When we introduces [persistent node ids](https://github.com/elastic/elasticsearch/pull/19140) we were concerned that people may copy data folders from one to another resulting in two nodes competing for the same id in the cluster. To solve this we elected to not allow an incoming join if a different with same id already exists in the cluster, or if some other node already has the same transport address as the incoming join. The rationeel there was that it is better to prefer existing nodes and that we can rely on node fault detection to remove any node from the cluster that isn't correct any more, making room for the node that wants to join (and will keep trying).
Sadly there were two problems with this:
1) One minor and easy to fix - we didn't allow for the case where the existing node can have the same network address as the incoming one, but have a different ephemeral id (after node restart). This confused the logic in `AllocationService`, in this rare cases. The cluster is good enough to detect this and recover later on, but it's not clean.
2) The assumption that Node Fault Detection will clean up is *wrong* when the node just won an election (it wasn't master before) and needs to process the incoming joins in order to commit the cluster state and assume it's mastership. In those cases, the Node Fault Detection isn't active.
This PR fixes these two and prefers incoming nodes to existing node when finishing an election.
On top of the, on request by @ywelsch , `AllocationService` synchronization between the nodes of the cluster and it's routing table is now explicit rather than something we do all the time. The same goes for promotion of replicas to primaries.
Adds `warnings` syntax to the yaml test that allows you to expect
a `Warning` header that looks like:
```
- do:
warnings:
- '[index] is deprecated'
- quotes are not required because yaml
- but this argument is always a list, never a single string
- no matter how many warnings you expect
get:
index: test
type: test
id: 1
```
These are accessible from the docs with:
```
// TEST[warning:some warning]
```
This should help to force you to update the docs if you deprecate
something. You *must* add the warnings marker to the docs or the build
will fail. While you are there you *should* update the docs to add
deprecation warnings visible in the rendered results.
AbstractQueryTestCase parses the main version of the query in strict mode, meaning that it will fail if any deprecated syntax is used. It should do the same for alternate versions (e.g. short versions). This is the way it is because the two alternate versions for ids query are both deprecated. Moved testing for those to a specific test method that isolates the deprecations and actually tests that the two are deprecated.
Factor rounding and Interval rounding (the non-date based rounding)
was no longer used so it has been removed. Offset rounding has been
retained for no since both date based rounding classes rely on it
When closing a transport client that depends on Netty 4, interrupted
exceptions can be thrown while shutting down some Netty threads. This
commit refactors the handling of these exceptions to finish shutting
down and then just restore the interrupted status.
Today if the PreBuiltTransportClient is using Netty 4 transport, on
shutdown some Netty 4 threads could linger. This commit causes the
client to wait for these threads to shutdown upon termination.
This change does three things:
1. Makes PreBuiltTransportClientTests run since it was silently
failing on a missing dependency
2. Makes PreBuiltTransportClientTests pass
3. Removes the http.type and transport.type from being set in the
transport clients additional settings since these are set to `netty4` by
default anyway.
