`KafkaUser` CR Designer UI

[tomncooper]

KafkaUser CRs similarly have many settings with which users would benefit from guidance, particularly the ACL (SimpleAuthorizer) configuration.

Crafting correct ACL sets is difficult and checking that a given set actually blocks/allows given operations is a deploy-and-see affair.

We should explore what a KafkaUser CR design UI would look like, how can we simplify the ACL creation/edit process and provide tooling for checking a given ACL configuration allows/blocks a given operation. For example:

• Does this ACL set allow user "Bob" to produce transactional messages to topics beginning with pii-*
• Does this ACL set prevent user "Alice" from consuming messages from any topic beginning with pii-*

All comments welcome.

Work still to do: add the ACL viewer to existing kafka users.

In comparison to your description in this issue @tomncooper this design implies that your bullet points would be worded:

• Does user "Bob" have permission to produce transactional message to topics beginning with pii-*
• Does user "Alice" not have permission to consume messages from any topic beginning with pii-*

As in the entry point is the user, not the ACL.

Actually I think a better wording would be:

• Does the set of ACL rules in this KafkaUser CR allow the principal "Bob" to produce transactional messages to topics beginning with pii-*
• Does the set of ACL rules in this KafkaUser CR prevent the principal "Alice" from consuming messages from any topic beginning with pii-*
