BGPaaS: deletion of BGPaaS obj does not delete back ref from VMI

[amit surana]

3.0 b 2684

Even after BgpAsAService object is deleted, the VMI still holds a back-ref to it. This VMI will continue to hold the back-ref to a non existent BgpAsAService object even if new one is attempted to be associated to it.

            bgpaas_obj.del_virtual_machine_interface(vmi)
            self._vnc_lib.bgp_as_a_service_update(bgpaas_obj)
            self._vnc_lib.bgp_as_a_service_delete(id=bgpaas_obj.uuid)

Fix multiple issues with properties validation

1. At couple of places, obj type needed to be converted to underscore instead of dash
2. Wrong variable name was used at one place (prop_dict instead of prop_value)
3. Schema transformer should set asn as integer instead of string
4. Wrong varialble name was used at two places in schema transformer
