parallel execution - beaker provisioner (mrack): name 'ProvisioningError' is not defined

[jscotka]

appeared inside PR: #3265
seems there is some trouble with python namespace and parallelization of plans.
There will be some trouble with imports inside the code.

As we've discussed with @happz it could be something what just parallelization highlighted. Parallelization itself does not touch these specific plugins and virt/container plugins works for Miloš.
