Refactor polling methods in tests

[mkam]

Description

There are various "WaitFor" (WaitForEvent, WaitForTestReadiness, WaitForCatalogRegistration, etc.) methods that our tests use which poll an API until a certain condition is met. They mostly all follow a similar pattern and could be refactored to use common code for the polling setup. This would help reduce the bootstrap code needed to implement polling methods in the future.

Additional context

Noting some differences between the methods that may affect writing a common polling logic method.

• Some methods can benefit from returning the resource they're polling
• Some methods fail the test if the timeout is reached and some return an error
