devstack config for dogpile cache
Cause devstack to configuration a [cache] section in ceilometer.conf if CEILOMETER_CACHE_BACKEND is set. Currently set to default to using dogpile.cache.redis and a redis server on localhost. This options are not sufficient for generic use as the "backend_argument"s are not controlled. For general use it is probably best that tools just modify their local.conf to post config ceilometer.conf. Change-Id: I058e60f9440350f80262039171716a3ceb4dec62
