Alex Vandiver 55c0e670d9 cache: Only cache list results of QuerySets, not the QuerySet itself.
Storing a QuerySet rather than the list version of the result in it
has a large overhead -- and, as noted by the type annotations, the
result is only ever used as a list.  This difference is particularly
important because the cached `get_realm_user_dicts` can get extremely
large for realms with large numbers of users, potentially overflowing
the 1MB default object limit in memcached.

Switch all cases of `cache_with_key` which return QuerySets to
returning the list values of them.
