    Add support for external load-balancers

    Add new hiera configuration key 'external_lb'. If it's set to
    true then we should not configure Haproxy LB on controllers and
    also we should switch 'haproxy_backend_status' to 'http' provider.

    We calculate 'external_lb' during 'globals.pp' task - if we have
    no VIPs with 'haproxy' namespace, then it's set to 'true'.

    It does not change the default deployment scheme.

    Also fixing minor issue with default provider for
    'haproxy_backend_status' type.
