This change adds get_workload() to ImpalaTestSuite and removes it from all test suites that already returned 'functional-query'. get_workload() is also removed from CustomClusterTestSuite which used to return 'tpch'. All other changes besides impala_test_suite.py and custom_cluster_test_suite.py are just mass removals of get_workload() functions. The behavior is only changed in custom cluster tests that didn't override get_workload(). By returning 'functional-query' instead of 'tpch', exploration_strategy() will no longer return 'core' in 'exhaustive' test runs. See IMPALA-3947 on why workload affected exploration_strategy. An example for affected test is TestCatalogHMSFailures which was skipped both in core and exhaustive runs before this change. get_workload() functions that return a different workload than 'functional-query' are not changed - it is possible that some of these also don't handle exploration_strategy() as expected, but individually checking these tests is out of scope in this patch.
