Removes ACL edits from e2e tests in favour of trying to simplify the tests and separate the actual test logic from the environment setup logic as much as possible. Also aims to fit in with the requirements that will generally be filled anyway for most devs working on the operator; in particular using tags that fit in with our documentation.
