Modify operator to use profiles to create pods in other clusters/namespaces

Now the controller has access to profile, the operator can use the profiles to create pods for script and container templates in other clusters and namespaces.

Start by tracing how the controller currently accesses profiles and how it creates pods for script and container templates. Identify the paths responsible for selecting clusters and namespaces, then determine the expected behavior for using profiles to target both. Done means those templates can create pods in other clusters and namespaces through the available profiles, with appropriate validation demonstrated by the existing test suite.
