Separate keyspace which also behaves as system brings
little benefit while creating some compatibility problems
like schema digest mismatch during rollback. So we decided
to move auth tables into system keyspace.

[avi: adjust test/alternator/suite.yaml to reflect new keyspace]
This commit includes updates related to replacing system_auth with system_auth_v2.
- The keyspace name system_auth is renamed to system_auth_v2.
- The procedures are updated to account for system_auth_v2.
- No longer required system_auth RF changes are removed from procedures.
- The information is added that if the consistent topology updates feature
was not enabled upon upgrade from 5.4, there are limitations or additional
steps to do (depending on the procedure).
The files with that kind of information are to be found in _common folders
and included as needed.
- The upgrade guide has been updated to reflect system_auth_v2 and related impacts.
