    Fix functional regression/recreate test for bug 1671648

    There are a couple of issues with the test:

      1. It doesn't consider both hosts from the two compute services
         during scheduling.

      2. There is a race where sometimes claims.Claim.__init__ won't
         be called because if the RT instance_claim runs before
         update_available_resource has run, it will create a
         claims.NopClaim instead.

    This adds the RetryFilter to enabled_filters, adds set_nodes() calls
    to set the nodenames of each compute service to match its host,
    resulting in consideration of both hosts for scheduling, and stubs
    resource_tracker.ResourceTracker.instance_claim instead of
    claims.Claim.__init__.
