---------------------------------------------------------------------

Blake was out for a while so I took over the metadata refactor. [This branch|https://github.com/aweisberg/cassandra/tree/14405-replicas-rebased]
is what we are using now and it's the base for  CASSANDRA-14406, CASSANDRA-14407, and CASSANDRA-14408
which we plan to merge to trunk together with the metadata refactor once complete. I don't
want to merge the metadata refactor alone since it's a bit silly if you can't even read and
write with transient replication.

The metadata refactor has been reviewed by [~ifesdjeen] and myself so far.

> Add support to CQL and NTS for configuring keyspaces to have transient replicas.
> Add syntax allowing a keyspace using NTS to declare some replicas in each DC as transient.
> Implement metadata internal to the DB so that it's possible to identify what replicas
are transient for a given token or range.
> Introduce Replica which is an InetAddressAndPort and a boolean indicating whether the
replica is transient. ReplicatedRange which is a wrapper around a Range that indicates if
the range is transient.
> Block altering of keyspaces to use transient replication if they already contain MVs
or 2i.
> Block the creation of MV or 2i in keyspaces using transient replication.
> Block the creation/alteration of keyspaces using transient replication if the experimental
flag is not set.
> Update web site, CQL spec, and any other documentation for the new syntax.
