    Add new provider for backend status checks

    Haproxy backend status check remains the default provider. Adding
    new one for basic HTTP checks so it could be possible to use
    external non-haproxy load balancers. After this we can make provider
    for haproxy_backend_status in our manifests conditional, based on
    whether we have external balancer or not.
