Now that the schema is fixed for all of the plugins, there isn't a need to delete and recreate the entire schema for every unit test. This patch clears the tables at the end of each test instead of deleting them. This eliminated overhead seems to save 10%+ execution time of the entire set of unit tests. Example of performance gain from tox -epy27 tests.unit.ml2: Before: Ran 2495 tests in 284.186s After: Ran 2495 tests in 223.299s Change-Id: Ic5bcbb0cf941e0745890abc776d719e58bb42e35
