Comment 1 for bug 1544074

These are scenario tests for convergence code(https://review.openstack.org/#/c/203661/).
It acts on fake_resources only.

It could be moved to functional tests, but since it takes less than a minute and till the time all convergence bugs are fixed and convergence is made the default option, I think it is fine to have it here so that dev will uncover bugs in early stage. (I assume not everyone runs the actual integration tests before submitting code)
