Add tests for keystoneclient python API interfaces

Registered by Steven Hardy

Prompted by ayoung's request in https://review.openstack.org/#/c/48462/, I've been adding some initial tests to provide coverage and end-to-end testing of the python API provided by keystoneclient.

The benefits are:
- Real end-to-end testing against a live server, provides better coverage than unit and integration tests where so much is mocked real bugs are sometimes missed
- Test interfaces which aren't exposed via the keystoneclient CLI (e.g trusts)
- Test functionality which is difficult or impractical to test purely via unit/integration tests
- Expose compatibility issues, where keystone tests pass, as to keystoneclient tests, but they don't work together.
