devstack: enable c-api,c-bak,c-sch,c-vol,cinder

With DEVSTACKGATERC modification, c-api,c-bak,c-sch,c-vol,cinder
are disabled so that some tests are skipped.
Add them back to enabled services to run them.
ceilometer and swift were also deleted, but they aren't related
to network directly, so they'll be dropped.
