Description
Im facing an issue when trying to get all consumer groups and topics under a kafka cluster through the HTTP endpoints:-
`/v3/kafka/(cluster)/consumer` and `/v3/kafka/(cluster)/consumer/(group)`
Everytime burrow is restarted (using kill -1 and running the process again), the output of the above endpoints will initially display empty lists and then slowly start to update with actual amount of consumers/topics over the period of next 5-10 seconds.
Is this intended behaviour or burrow can get incomplete data from kafka clusters ?

Research direction
Reproduce a restart and poll the `/v3/kafka/(cluster)/consumer` and `/v3/kafka/(cluster)/consumer/(group)` endpoints during the first 10 seconds. Trace how these endpoints populate their consumer and topic lists, then determine whether the delayed update is intended behavior or incomplete Kafka data; document the expected result.
