Add PostgreSQL support to devstack This patch adds an interface for supporting multiple database backend types and implemnts support for PostgreSQL. It also adds a function, use_exclusive_service, which serves as a base for enabling a service that conflicts with other services. The use_database function uses it, and it might also be useful for selecting messaging backends. MySQL is still selected by default. Tested on Fedora 17 and Ubuntu 12.04 with MySQL and PostgreSQL.

Config for ceilometer gathering from glance Some changes are required so that ceilometer can gather usage data from glance (notification & polling) out-of-the-box in devstack: - configure glance to emit notifications if rabbitmq or qpid is enabled - configure the ceilometer collector to consume notifications on the default glance topic (glance_notifications.*) - pass credentials to ceilometer central agent so that it authtenticate polling calls to glance Change-Id: I0eac223eddb615266e28447b18fcaaadcd40dddf
