Request to list REST API versions doesn't return the request id

[Gorka Eguileor]

When we do a GET on the root of the REST API service to get available versions we don't get any of the expected request id headers.

These headers are "x-openstack-request-id" and "x-compute-request-id" for both Cinder and Nova.

    Fix request id mess on Cinder-API

    This patch fixes multiple issues related to request ids:

    - Duplicated request ID in logs
    - Missing request id header in response
    - Wrong request ID in response header when using noauth

    The source of these issues is the fact that the request ID and the
    request context are set too late, or not at all, in the paste filter
    chain.

    And the last bug is fixed as a freebie when the code in auth.py is
    refactored to reduce code duplication on setting the cinder.context key
    in the request's environment.

    The patch fixes these issue by changing the filter chains to have the
    request_id filter as the first filter, and using our own filter for it,
    to ensure that the context is correctly set.

    Not sure if values now defined in ENV_OVERWRITES are still necessary,
    so the patch preserves current behavior.
