Refactored test framework so that we have more flexibility in terms of installing various versions of microstack before and after running some tests. Moved in class "globals" into per instance variables, to avoid broken cases with incomplete cleanup. Added test_refresh.py, plus matching env in tox. Refresh tests will fail currently, because we have some pending issues that break refreshes. Fixing those is a subject for a different commit. Refactored cluster_test.py and control_test.py to use new framework. Should (and do) pass. Framework now cleans up multipass hosts regardless of whether or not the tests passed. Leaning on the .tar.gz for local troubleshooting helps us make it better for in gate troubleshooting. Change-Id: I6a45b39132f5959c2944fe1ebbe10f71408ee777

This is a test to verify that we can setup a small, two node cluster.

The host running this test must have at least 16GB of RAM, four cpu

cores, a large amount of disk space, and the ability to run multipass

vms.
