Fix grenade job for mod_wsgi to uwsgi transition
This patch updates the grenade job to migrate from using Apache mod_wsgi to using uwsgi for the Designate API when upgrading from Xena to Yoga. It also splits out the wsgi devstack configuration into a library file. Change-Id: Icf8ee4a8e7e2dff67257b0e5f82fbeab6cb7e0b8
