Fixing instability in tests
Fixing instability in tests

This change modifies how some of the kontainer-engine validation tests were
running to make sure they wait for the `provisioned` condition to appear on
the cluster before asserting that a value is present.  Before this change a
race condition was present and sometimes the tests would fail unnecessarily.
