add functional tests for identity v3

To make test cases more clearly, split test_identity.py
into test_user.py, test_role, etc. Add more test cases for
user, role, etc. Furthermore, to make functional tests run
repeatedly without raising duplicated error, clean up
resources before exiting each test case.
