Add grantable MAINTAIN privilege and pg_maintain role.
Allows VACUUM, ANALYZE, REINDEX, REFRESH MATERIALIZED VIEW, CLUSTER, and LOCK TABLE. Effectively reverts 4441fc7. Instead of creating separate privileges for VACUUM, ANALYZE, and other maintenance commands, group them together under a single MAINTAIN privilege.
