    Fix test_request_no_token_dummy cms dependency.

    * tests/test_auth_token_middleware.py: test_request_no_token_dummy has a
    dependency on the keystone.common.cms module importing subprocess prior
    to running. The cms._ensure_subprocess() function does this. Call this
    function in the base test class's setUp method to ensure subprocess is
    imported before symbols from that module are needed. Doing this in the
    base setUp will ensure that this works for any additional tests with the
    same dependency.

    This fix is needed because testr runs tests in non deterministic order
    which means that each test needs to be able to run on its own (eg in its
    own process without any other tests running first) and they need to run
    without interfering any other tests (each test must properly clean up
    after itself). Prior to this commit test_request_no_token_dummy would
    fail when executed on its own.
