Add svc-map to cinder-api

This patch integrates svc-map into the cinder-api element
by adding a svc-map yaml file and updating os-svc-* calls
to use the -a option so svc-map is called instead of
map-services.  Please see the svc-map integration commit[1]
for more information on implementation details as needed.
