The stream SAC coordinator already keeps track of its monitors but delegates some of the work to the stream coordinator (in its monitors map). This commit changes this to let the SAC coordinator handle its monitors itself. This decouples the 2 coordinators. This also fixes a bug whereby the SAC coordinator would correctly re-issue monitors but would not modify the monitors map accordingly. The SAC coordinator would not then be notified of the corresponding down messages. References rabbitmq/rabbitmq-stream-dotnet-client#447
The function is meant to be used by an operator as a last resort to
clean up a consumer group from "ghost" consumers and unblock the group.
At this point the SAC coordinator should work as expected but an upgrade
from a version with known issues can end up with blocked groups. So this
function should help unblock the groups manually.
It can be called like this:
rabbitmqctl eval 'rabbit_stream_coordinator:evaluate_sac_group(<<"/">>,
<<"stream-0">>,
<<"app1">>).'
