Avi Kivity bbad8f4677 replica: move ::database, ::keyspace, and ::table to replica namespace
Move replica-oriented classes to the replica namespace. The main
classes moved are ::database, ::keyspace, and ::table, but a few
ancillary classes are also moved. There are certainly classes that
should be moved but aren't (like distributed_loader) but we have
to start somewhere.

References are adjusted treewide. In many cases, it is obvious that
a call site should not access the replica (but the data_dictionary
instead), but that is left for separate work.

scylla-gdb.py is adjusted to look for both the new and old names.
