Dawid Medrek 749197f0a4 cql3/alter_keyspace_statement: Do not allow for change of RF by more than 1
We want to ensure that when the replication factor
of a keyspace changes, it changes by at most 1 per DC
if it uses tablets. The rationale for that is to make
sure that the old and new quorums overlap by at least
one node.

After these changes, attempts to change the RF of
a keyspace in any DC by more than 1 will fail.
