Sahil Batra 764f4aa2e0 groups: Use realm_for_sharding for limiting NamedUserGroup queries. 
For get and filter queries of NamedUserGroup, realm_for_sharding
field is used instead of realm field, as directly using
realm_for_sharding field on NamedUserGroup makes the query faster
than using realm present on the base UserGroup table.

"""
If we are assigning colors to a user with 24+ streams, we have to start
reusing old colors. Our algorithm basically uses recipient_id % 24, so
the following code reflects the worse case scenario that our new
streams have recipient ids spaced out by exact multiples of 24. We
don't try to work around this edge case, since users who really depend
on the stream colors can always just assign themselves custom colors
for the streams that they really want to stand out.
Even if recipient_ids were completely random, the odds of collisions
are low, but it's often the case that bulk-adds are done for streams
that either were or are being created at roughly the same time, so the
recipient_ids tend to have even fewer collisions.
