Based upon the established conf paradigm used in Nova, this patch moves most of the configuration to a central location. Making config a lot easier to manage, as well a lot easier to locate. There is still some configuration listed in classes, that I would like to eventually move to designate.conf as well, but to lower complexity not all config was moved. General changes * Centrelized most configuration under designate.conf. * Cleaned up configuration. * Simplified config generation. * Renamed generated config to designate.conf.sample. Previously broken * xfr_timeout now in the appropriate section. * memcached_servers now in the appropriate section. Previously missing from sample config * allowed_remote_exmods listed in sample config. * backend:akamai section listed in sample config. * backend:dynect section listed in sample config. * backend:infoblox section listed in sample config. blueprint centralize-config-designate Change-Id: I3be68bf294157631a9bac128df0841220020de96
