+1 

An openstack request id should be service agnostic to allow tracking of a request across many services (e.g. a call to nova to boot a VM should generate a request id that is provided to other services in requests to provision said VM).  All services would ideally share a facility for generating new request ids and for securely accepting request ids from other services.
