noauth should also use request_id generated from compute_req_id

[Zhenyu Zheng]

When using noauth midlleware, the context is generated here:
https://github.com/openstack/nova/blob/ef6f4e4c8ec82e2c9f9988fe2e04591ee01220e6/nova/api/openstack/auth.py#L56
as the openstack.request_id from req.environ, previously created in:
https://github.com/openstack/oslo.middleware/blob/master/oslo_middleware/request_id.py#L57
was not included in the initialize of the context obj, nova will generate a new request_id for context obj.

As the req.environ['openstack.request_id'] will latter returned to user as the 'x-openstack-request-id'
field in the response header, users may use this for searching etc. But the latter Nova workflow will
all use the context.request_id, which will lead to an inconsistency problem.
