Moves the test_catalog_hms_failures.py and test_process_failures.py from the experimental tests to custom cluster tests. catalog_service/test_hms_failure.py is combined with custom_cluster/test_catalog_hms_failure.py as well in order to unify all tests for HMS failures. Several modifications to the tests were necessary to get them working again, but for the most part, the logic of the tests remained the same. A few additional fault tolerance tests (e.g. TestHiveMetaStoreFailure::test_hms_client_retries) were added as well. The overall goal is to increase the process failure test coverage for all components: impalads, statestore, catalogd, HMS, etc. test_restart_catalogd in test_process_failures.py fails due to IMPALA-9848, so it is skipped for now.
