Configure nova to use service user tokens
Long-running operations such as live migration or snapshot can
sometimes overrun the expiry of the user token.
In such cases, post operations such as cleaning up after a live
migration can fail when the nova-compute service needs to cleanup
resources in other services, such as in the block-storage (cinder)
or networking (neutron) services.
This patch enables nova to use service user tokens to supplement
the regular user token used to initiate the operation.
The identity service (keystone) will then authenticate a request
using the service user token if the user token has already expired.
