Changes the behavior of default superuser creation.
Previously, without configuration 'cassandra:cassandra' credentials
were used. Now default superuser creation is skipped if not configured.
The two ways to create default superuser are:
- Config file - auth_superuser_name and auth_superuser_salted_password fields
- Maintenance socket - connect over maintenance socket and CREATE/ALTER ROLE ...
Behavior changes:
Old behavior:
- No config - 'cassandra:cassandra' created
- auth_superuser_name only - <name>:cassandra created
- auth_superuser_salted_password only - 'cassandra:<password>' created
- Both specified - '<name>:<password>' created
New behavior:
- No config - no default superuser
- Requires maintenance socket setup
- auth_superuser_name only - '<name>:' created WITHOUT password
- Requires maintenance socket setup
- auth_superuser_salted_password only - no default superuser
- Both specified - '<name>:<password>' created
