Enable ServerGroup scheduler filters by default

The Icehouse release includes a server group REST API. For these
groups to actually function properly, the server group scheduler
filters must be enabled. So, these filters should be enabled by
default since the API is also enabled by default. If the API is not
used, the scheduler filters will be a no-op.

Reduce config access in scheduler

Caching the configuration appears to make a impact on the time spent
in the scheduler. These config values reduce the time spent down from
around 5ms to around 4ms per request, when with 200 hosts.
