Service token will be passed along with user token to communicate with services when dealing with long running tasks like live migration. This change addresses adding service_token to the request when nova requests neutron session. Implements: blueprint use-service-tokens Change-Id: I5e6d6dfeda3673d38bab0bc692c50ca74eb90fc1

When True, if sending a user token to an REST API, also send a service token.

|
Nova often reuses the user token provided to the nova-api to talk to other
|
|
REST APIs, such as Cinder and Neutron. It is possible that while the
|
|
user token was valid when the request was made to Nova, the token may expire
|
|
before it reaches the other service. To avoid any failures, and to
|
|
make it clear it is Nova calling the service on the users behalf, we include
|
|
a server token along with the user token. Should the user's token have
|
|
expired, a valid service token ensures the REST API request will still be
|
|
accepted by the keystone middleware.

This feature is currently experimental, and as such is turned off by default
|
|
while full testing and performance tuning of this feature is completed.
