Change ACL modification mechanism in Console

[jason-da-redpanda]

Currently in console when ACL's are modified, we delete the existing ones.. then recreate with existing acls + additions.

We have seen this can cause problems on clients ...

Have been able to reproduce consistently with following steps :

• In Console configure acls for a user-A. . give permisions for topic-1, + consumergroup1. (then repeat with topic2, consumer group2 ... up to 5 sets of resources for topic + group) [Save/ok]

• Start java consumer. Confirm it's reading from topic1 , Group 1 running.. + no issues with authorisation.

• In console Amend ACL's for user-A.. Give additional permissions for topic6 + consumergroup6. [Save/ok]

• Java Consumer now fails with auth errors
  Java log :
  [com.redpanda.ConsumerExample.main()] WARN org.apache.kafka.clients.consumer.internals.Fetcher - [Consumer clientId=consumer-firefox-1, groupId=firefox] Not authorized to read from partition topic-1-0. org.apache.kafka.common.errors.TopicAuthorizationException: Not authorized

• Restart java consumer no issues with ACLS / authorisation

• The ACL's are as expected in consol/rpk acl list...e.g the additional topic/group was added we didnt lose any

Requested Feature change :
Either :

1. change the UI for ACLs significantly
2. make console smarter so that it can do better diffs without removing
