By default the reroute API should return the new cluster state, excluding the metadata. It was however it was wrongly using an old parameter (filter_metadata) and thus failed to do so. This commits restores but wiring it to the correct `metric` parameter. We also add an enum representing the possible metrics, to avoid similar future mistakes.
Closes#7520Closes#7523
The functionality of copying headers in the REST layer (from REST requests to transport requests) remains the same. Made it a bit nicer by introducing a RestClientFactory component that is a singleton and allows to register useful headers without requiring static methods.
Plugins just have to inject the RestClientFactory now, and call its `addRelevantHeaders` method that is not static anymore.
Relates to #6513Closes#7594
Also renamed HeadersCopyClientTests since it tests a class that was renamed and removed randomization around client wrapper, as it now needs to be weapped all the time to copy the context, doesn't depend on useful headers that have been registered anymore.
Relates to #7610
Today we throw an error if local transport is configured with BWC tests.
Yet, the BWC test need network to be enabled so test can just set the
required defaults.
Closes#7660
Previously we incorrectly sent them in the wrong order, which can cause
validators not to be run for dynamic settings that have been added
matching a particular wildcard.
Fixes#7651
get rid of readSource() entirely, it sucked, Operations should be able
to provide the source themselves.
No more TranslogStream headers, you are now required to pass an
StreamInput or StreamOutput for all operations, which means no extra
state is needed and no need to construct new versions when detecting the
version.
Read and write translog op sizes in TranslogStreams
Previously we handled these integers outside of the translog stream
itself, which was very unclean because other code had to know about
reading the size, or about writing the correct header sometimes.
There is some additional code in LocalIndexShardGateway to handle the
legacy case for older translogs, because we need to read and discard the
size in order to maintain the compatibility for the streaming
operations (they did not read or write the size for 1.3.x and earlier).
Additionally, we need to handle a case where the header is truncated
when recovering from disk
Use a NoopStreamOutput instead of byte arrays
Instead of writing translog operations to a temporary byte array and
then writing that byte array to the stream, we now write the operation
twice, once to a No-op stream to get the size, then again to the real
size.
This trades a little more CPU usage for less memory usage.
Today we serialize the snashot metadata to a byte array and then copy
the byte array to a stream. Instead this commit moves the serialization
directly to the target stream without the intermediate representation.

Before the heapdump was either written in a file with the
directory name if the heapdump path ended without / or
not written at all if the path ended with /

We keep around a noop stats indicating how many update operations ended up not updating the document (typically because it didn't change). However, the TransportUpdateAction update that counter only after returning the result. This can throw off stats check which are done immediately after, potentially causing test failures.
Closes#7639
Today there are two different ways to cleanup search contexts which can
potentially lead to double releasing of a context. This commit unifies
the methods and prevents double closing.
Closes#7625
Updates on the _timestamp field were silently ignored.
Now _timestamp undergoes the same merge as regular
fields. This includes exceptions if a property cannot
be changed.
"path" and "default" cannot be changed.

The terms aggregation can now support sorting on multiple criteria by replacing the sort object with an array or sort object whose order signifies the priority of the sort. The existing syntax for sorting on a single criteria also still works.
Contributes to #6917
Reduce Phases can be expensive and some of them like the aggregations
reduce phase might even execute a one-off call via an internal client
that might cause a deadlock due to execution on the network thread
that is needed to handle the one-off call. This commit dispatches
the reduce phase to the search threadpool to ensure we don't wait
for the current thread to be available.
Closes#7623
Lucene's experimental codecs (from the codecs module) do not provide
backwards compatibility and are free to change from release to
release. When they do change, they typically cannot in general read
older indices and the resulting exceptions look like index corruption.
So, we are removing built-in support for them to prevent applications
from choosing one and then seeing strange exceptions on upgrade.
