This patch series removes creation of default 'cassandra:cassandra' superuser on system start.
Disable creation of a superuser with default 'cassandra:cassandra' credentials to improve security. The current flow requires clients to create another superuser and then drop the default `cassandra:cassandra' role. For those who do, there is a time window where the default credentials exist. For those who do not, that role stays. We want to improve security by forcing the client to either use config to specify default values for default superuser name and password or use cqlsh over maintenance socket connection to explicitly create/alter a superuser role.
The patch series:
- Enable role modification over the maintenance socket
- Stop using default 'cassandra' value for default superuser, skipping creation instead

This is an improvement. It does not need a backport.
