    VMware NSX: Fix DVR operations

    The switch to the community management layer mixin introduced
    several bugs in the NSX-mh plugins.
    This patch:
    1) Stops creating centralized SNAT interfaces for NSX distributed
       routers. The NSX backend does not need those and they therefore
       only waste IPs and create confusion. This is done by providing
       an empty implementation for the relevant methods.
    2) Does not query l3-agents when removing router interface. This
       is causing errors during interface removal and preventing router
       removal, as the NSX plugin does not use l3 agents at all.
       This patch provides an empty implementation for the relevant
       method thus preventing the DVR mixin from doing any sort of
       operations pertaining l3 agents.
    3) It ensures DVR router interfaces are taken into account in the
       management of metadata network for routers.
