Dario Mirovic 5d51501a0b pgo: use maintenance socket for CQL setup in PGO training ...

The default 'cassandra' superuser was removed from ScyllaDB, which
broke PGO training. exec_cql.py relied on username/password auth
('cassandra'/'cassandra') to execute setup CQL scripts like auth.cql
and counters.cql.

Switch exec_cql.py to connect via the Unix domain maintenance socket
instead. The maintenance socket bypasses authentication, no credentials
are needed. Additionally, create the 'cassandra' superuser via the
maintenance socket during the populate phase, so that cassandra-stress
keeps working. cassandra-stress hardcodes user=cassandra password=cassandra.

Changes:
- exec_cql.py: replace host/port/username/password arguments with a
  single --socket argument; add connect_maintenance_socket() with
  wait ready logic
- pgo.py: add maintenance_socket_path() helper; update
  populate_auth_conns() and populate_counters() to pass the socket
  path to exec_cql.py

Fixes SCYLLADB-1070

Closes scylladb/scylladb#29081
