    heat api : Update ec2token middleware for v4 signatures

    Update ec2token so it can verify v4 signature formats.

    Note for v4 signatures to work you need keystone to be using
    python-keystoneclient >= 0.2.4, or contain the patch from
    https://review.openstack.org/#/c/26013/

    This change is backwards compatible, as older keystoneclient
    versions will simply ignore the additional request keys

    fixes bug #1122472
