Provide a simple create domain test that uncovered a bug with an
exception in addition to fixing the tests to avoid unnecessary output
when the code sends messages via the UI.
Add basic spec tests for the domain template to test rendering through
simple wrapping of a config object to provide values for class instance
variables used by the template as it mostly mirrors those required.
Add some basic spec tests for the WaitTillUp action class to lay some
foundations. Utilize vagrant-spec pinned to a known working commit for
tests to pass consistently until they provide releases.
Requires updating some of the rspec libraries and includes
sharedcontext.rb from the jantman/vagrant-r10k project on github.
