Adds new parametrization to the unique database fixture: - num_dbs: allows creating multiple unique databases at once; the 2nd, 3rd, etc. datbase name is generated by appending "2", "3", etc., to the first database name - sync_ddl: allows creating the dabatases(s) with sync_ddl which is needed by most tests in test_ddl.py Testing: I ran debug/core and debug/exhaustive on HDFS and core/debug on S3. Also ran the test locally in a loop on exhaustive.
