move s3_token middleware to keystoneclient

[Adam Young]

s3_token middleware is in keystone, and needs to be moved to the keystoneclient project just like we moved the auth_token middleware.

The following proposal will address the issue mentioned in the bug.

    Copy s3_token middleware from keystone

    The s3_token middleware was in keystone but it should be in
    python-keystoneclient. As a first step to removing s3_token from
    keystone, copy it to python-keystoneclient. Also copy the tests.

    A couple of changes were required

    - Changed oslo-incubator imports from keystone to keystoneclient.
    - Changed logging from oslo-incubator to use Python logging and
      configured the same way as the auth_token middleware.

    I checked and I didn't see anything to be added to requirements.txt
    or test-requirements.txt.

Since this is committed to python-keystoneclient, when there's a new release I can update keystone to import and deprecate.
