Add openvswitch-common to neutron-api/consolidated rocks

The neutron-api package now runs under apache+mod_wsgi instead of as a
standalone neutron-server process. When mod_wsgi imports the WSGI
application, neutron.server.api publishes a PROCESS/BEFORE_SPAWN event
on every worker fork, which triggers OVNMechanismDriver.pre_fork_initialize.
That callback shells out to ovsdb-client which was missing previously.
