Cleanup command fails to drop pglogical role due to privileges on view `pg_stat_statements`

[vjeeva]

Describe the bug
PgBelt fails to drop the pglogical role when running belt teardown --full with the following error:

ERROR:  role "pglogical" cannot be dropped because some objects depend on it
DETAIL:  privileges for view pg_stat_statements

Expected behavior
The teardown command runs without errors and doesn't stop in the middle.

Additional context
This happened with a Postgres 12 RDS database.

Solution - just gotta run an extra REVOKE to get rid of the blocker:

REVOKE ALL ON pg_stat_statements FROM pglogical;
