Restore and split nova metadata docker service out of nova-api.

I2c39a2957fd95dd261b5b8c4df5e66e00a68d2f7 changed nova api to http from
eventlet, however we need to continue running the eventlet service as
it is required for the nova metadata api.

However this should be tied to the OS::TripleO::Services::NovaMetadata
service, so duplicate the required config in nova-metadata.yaml.
