cyrusv opened a new pull request #4875: KAFKA-6788: Grouping consumer requests 
per consumer coordinator in admin client
URL: https://github.com/apache/kafka/pull/4875
   Resolves KAFKA-6788 for the deleteGroup case
   For the "describeGroup" case, we build a hash-set and `continue` when we 
have already described the group. The describe API lets us submit all groups so 
this is the only work we must do.
   For the "deleteGroup" case, we ask the Coordinator which groups it knows 
about, and delete those. Also use a hashset to `continue` over groups we have 
already deleted.
   Passes tests, no new testing or documentation necessary.

> In KafkaAdminClient, for some requests like describeGroup and deleteGroup, we 
> will first try to get the coordinator for each requested group id, and then 
> send the corresponding request for that group id. However, different group 
> ids could be hosted on the same coordinator, and these requests do support 
> multi group ids be sent within the same request. So we can consider optimize 
> it by grouping the requests per coordinator destination.
