Add some cleanup commands to the integration tests

Bad tests that panic won't clean themselves up properly.  By putting
these cleanup commands before we run the minikube integration tests, we
ensure that minikube will have a clean environment to run.

These all run in common.sh to make sure that even hypervisors that they
arent testing don't interfere with their own test.  OS specific
commands will fail silently.
