clique: Add the Clique runner to run all the Clique tests.

Initial draft of Clique runner which is based on the chaos_runner. This
is a very simplified skeletal version of the runner to get us started.
More changes will be incoming once we start writing more scenarios and
start real end to end testing.
Also adding some formatting cleanups in the other modules.
