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.
