    Make DvrServerRpcCallback a separate callback class

    RPC has a version of itself. In Neutron a plugin implements
    several RPC interface, so a single RPC version doesn't work.
    In Mixin callback class approach, RPC versioning depends on
    each plugin implementation and it makes harder to maintain
    RPC version appropriately. This patch series replaces mixin
    RPC callback of server side with a separate class.

    This commit handles server-side callback of DVR ML2 RPC interface.
