[RBAC] Disable inaccessible menu items

[armenuikafka]

Describe the bug
In case user doesn't have any permission for any block (Consumers f.ex.), the corresponding element in the left menu should be disabled

Set up
https://www.kafka-ui.provectus.io/

Steps to Reproduce

1. Make sure user doesn't have any permission for "Consumers"
2. Login to Kafka-ui
3. Check cluster components in a left

Expected behavior
The Consumers component should not be visible in a cluster slide bar

@Haarolean @armenuikafka Anyone working on this? I can give it a shot if not taken already. Also, do we have any documentation on how to enable RBAC for testing purpose?
