Description

burrow consumer group status is not updated in time
for example:

I'm manually delete the consumer group named test01.
after i did that, burrow still alert the test01 in state error. but there is no consumer group test01 exist.
only restart burrow can make consumer group status back to normal.
my questions is why burrow can not automatic detect the consumer group status ?

burrow version is `1.2.2`
kafka version is `2.1.1`

Research direction

Reproduce the stale consumer-group status with Burrow 1.2.2 and Kafka 2.1.1 by deleting the test01 group, then inspect how Burrow refreshes consumer-group state. Done means Burrow automatically removes or updates the deleted group and clears its error alert without requiring a restart.
