Add support for v1 clusters for users, roles, topics, and schemas

[andrewstucki]

This adds v1 cluster support for User, Role, Topic, and Schema types (topics haven't been moved to use ResourceController yet, so those haven't been touched). It modifies and extends our acceptance tests to be able to handle connections to v1 clusters and adds in a duplicate set of tests for Roles to ensure they work the same with v1 or v2 clusters.

The flag for having v1 cluster support is the same as elsewhere, it just leans on the enable-vectorized-controllers option.

LGTM, but I don't see acceptance test for schema registry and topic custom resource.

[RafalKorepta]

Could this step be replaced with Topic custom resource. I understand test should as much as possible test isolated features/changes, but I think acceptance test suite can combine more custom resources under test.

@RafalKorepta for the other acceptance tests, I wanted to do those separately just to keep the initial implementation diff light while still exercising the majority of the code paths I changed. I’ll try and add the tests for the other resources as a follow up, but that may or may not also end up tacking on a bunch of time to our acceptance tests, so wanted to experiment some with structuring those.
