Use templating for nova cell database_connection
Nova now allows use of templated urls in the database and mq connections which will allow static configuration elements to be applied to the urls read from the database per-node. This should be a simpler and less obscure method of configuring things like the per-node bind_address necessary for director's HA arrangement. This patch addresses the templated DB urls as part 1.
