Run selected qtest on different metastore backends

In various cases there are bugs which affect only certain types of metastore databases (e.g., HIVE-26000) and it would be nice to be able to specify for each test or a bunch of tests which metastore backend to use and have these tests consistently running in CI.

After HIVE-21954, it is possible to run qtests on different metastores by setting the system property test.metastore.db or introducing new AbstractCliConfig configuration with a new driver etc.

The naive way of implementing this task would be to copy an existing configuration, change the metastore type, select the input files, and create a new driver (probably again a copy from CoreCliDriver.

Other ideas would be to allow a driver to run with multiple configurations, or handle the selection of the metastore type via QT options (similar to what was done in HIVE-25594).
