Make TransportGetSnapshotLifecycleStatsAction project aware

[samxbr]

Make TransportGetSnapshotLifecycleStatsAction project aware, also make it read from local cluster state instead of calling the master node since the state is available locally.

Thanks for cleaning this up, @samxbr! I left two comments regarding (de)serialization, but other than that it looks good to me :)

We don't actually need this transport version check (or the new transport version), as this branch will never fire. Any node that is on this transport version will execute the request locally, instead of forwarding it to the master node. Therefore, if we receive this request over the transport wire, we already know it's from an old node.

Also, we don't need this separate deserialization method, we can do this in the constructor like we do here:

elasticsearch/x-pack/plugin/core/src/main/java/org/elasticsearch/xpack/core/ilm/action/GetStatusAction.java

Lines 48 to 52 in d8257b4

	public Request(StreamInput in) throws IOException {
	super(in, false);
	// Read and ignore ack timeout.
	in.readTimeValue();
	}

We can also remove the Response(StreamInput in) constructor below, as we'll know for sure that we'll never have to deserialize a response anymore (because any node on this version will run the request locally).

And can you add a @UpdateForV10(owner = UpdateForV10.Owner.DATA_MANAGEMENT) line to the Response#writeTo method? When we get to V10, we won't need that method either anymore.
