Enable GlusterFS plugin to use devstack's override_defaults phase devstack now supports override_defaults phase, which helps plugin specify devstack variables that need to be overridden in override-defaults file. This patch make use of this feature so that devstack specific variables can be overridden by the end user based on the local setup being used. This patch also extends GlusterFS specific variables in settings file to use bash default syntax so those can be overridden too based on the local setup being used.
