Add e2e ests to Show deprecated operators in OperatorHub work. 

Open question:

What kind of tests would be most appropriate for this situation, considering the dependencies required for end-to-end (e2e) tests?

Dependencies:

• Create a CatalogSource resource
• Install a test operator i.e. Kiali Community Operator

AC:

• Add integration tests for both pre and post installation steps [2]
  • Here we should use Kiali Community Operator, which we should install though the CLI, so the test wont take to much of time.
