    The use-case is that, for some unspecified reason, the control plane
    has a different set of interface addresses than VPP
    currently has. The CP would thus like to 'replace' VPP's set
    only by specifying what the new set shall be, i.e. it is not
    going to delete anything that already eixts, rather, is wants any
    unspecified interface addresses to be deleted implicitly.
    The CP declares the start of this procedure with this replace_begin
    API Call, and when it has populated all addresses it wants, it calls
    the below replace_end API. From this point on it is of course free
    to add and delete interface addresses as usual.
    The underlying mechanism by which VPP implements this replace is
    intentionally left unspecified.
