Whenever chunks are created, no privileges are added to the chunks. For accesses that go through the hypertable permission checks are ignored so reads and writes will succeed anyway. However, for direct accesses to the chunks, permission checks are done, which creates problems for, e.g., `pg_dump`. This commit fixes this by propagating `GRANT` and `REVOKE` statements to the chunks when executed on the hypertable, and whenever new chunks are created, privileges are copied from the hypertable. This commit do not propagate privileges for distributed hypertables, this is in a separate commit.
