Modules import nova.config for two reasons right now - firstly, to reference nova.config.CONF and, secondly, if they use one of the options defined in nova.config. Often modules import nova.openstack.common.cfg and nova.config which is a bit pointless since they could just use cfg.CONF if they just want to nova.config in order to reference CONF. Let's just use cfg.CONF everywhere and we can explicitly state where we actually require options defined in nova.config. Change-Id: Ie4184a74e3e78c99658becb18dce1c2087e450bb
