Removed a warning message from automation log

We log a warning everytime a service model is not found. Which includes
basic ruby objects. e.g.

Created refactored x_button_response method so spec can stub it

Code was rendering responses due to test stubbing of actual button methods, so broke the rendering code out into a new method and stubbed that method in the spec.

Removed a warning message from automation log
Add support for service hierarchies

For multipart service deployments, parent/child
relationships between services can now be visualized
in the 'My Services' tree view.

The visibility of child services needs to be enabled
via the "display" attribute on MiqAeServiceService
for child services to appear in the hierarchy, by
default they are hidden. Also added an explicit
method for create new Service records via automation.
