[vitrage] Removing the static-physical datasource

Hi, Just wanted to give you a heads-up that we are about to remove the static-physical datasource [1][2] that was deprecated in Queens [3]. Please use the static datasource [4] instead. Thanks, Ifat [1] https://review.openstack.org/#/c/624033/ [2] https://review.openstack.org/#/c/624031/ [3] https://docs.openstack.org/releasenotes/vitrage/queens.html [4] https://docs.openstack.org/vitrage/latest/contributor/static-config.html
