Hi,

I wonder why nova-api or cinder-api aren't present service group API of each project:

mdulko:devstack/ (master) $ cinder service-list
+------------------+-------------------------------+------+---------+-------+----------------------------+-----------------+

Are there any technical limitations to include API services there? Use case is that when service dies during request processing - it leaves some garbage in the DB and quotas. This could be cleaned up by another instance of a service. For that aforementioned instance would need to know if service that was processing the request is down.
