Review Comment:
It was discouraged - we can do it ...
So, first we will send a list of all groups to GroupCoordinatorShard which
will return a list of delete requests only for VALID SHARE GROUPS. Other groups
will be ignored. This is the only extra work - we are only reading state from
the a hashmap.
