+++ This bug was initially created as a clone of Bug #1652118 +++

Description of problem:

In a scale container storage setup which hosts ~1000 1 X 3 volumes, its seen
that if a single brick process is going to host all the rest of 999 brick
instances, the overall footprint of the brick process might still be at the
higher side. We already have an option cluster.max-bricks-per-process which
when set to a value n, that's the max cap of number of brick instances to be
attached to a brick process. We have seen benefits in defining a cap of 250 of
bricks per process in few scale deployments where things haven't gone crazy
like glusterd taking lots of time to process disconnect events, bricks not
reaching to a warning level of OOM killer situation etc.
