......................................................................

Move the MetaCacheReplicaPicker into meta_cache.h/cc and make it a member of RemoteTablet

This moves the MetaCacheReplicaPicker into meta_cache.h/cc and makes it so
that one instance of the picked is shared by all users of a certain RemoteTablet.

The end result is that further improvement of the replica picker (for instance
to make it more of a part of RemoteTablet with a less redundant code path)
can be isolated from other components. batcher.cc no longer contains any
reference to the replica picking code.
