Bug Description

In the cinder-api logs we can find duplicated request ids, which may confound people.

Running the following 2 commands:

 $ cinder list
 $ cinder api-version

Will result in log entries with duplicated request ids.

In the following log entries, after running those 2 commands, we can see that there are 4 REST API requests but there are only 2 different request ids, as req-e5f2fe4b-bd80-4ccc-87ed-e97aa66d8a89 and req-8a27dec8-63de-400b-b955-04d459c104df appear twice each.

Something similar happens in nova, though an additional call to "nova version-list" is necessary to see it.

It's even easier to check just running multiple times (in devstack 4 times is enough) the curl command to query the root endpoint.

For Nova:
 curl -v http://<IP>/compute

For Cinder:
 curl -v http://<IP>/volume

    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.
