    Add retry to keystone_user.exists?

    Put back exists? method in keystone_user in line with the usual
    openstacklib mechanism. This is done by adding the possibility for
    request call to pass regexp messages that shouldn't be retried.

    Now we can safely call fetch_user without worrying about having the call
    retried by opentacklib.

    Fetch_project has the same behavior, so I added it to the mix. It may
    be a performance killer somewhere.
