    Make update_qos_minbw_allocation() more generic

    update_qos_minbw_allocation() function is used to update Placement
    allocation. Initially, only minimum bandwidth rule allocated resources
    in Placement, but with the introduction of minimum packet rate rule
    that's changed. Because of that, we should rename the function to make
    it more generic and to avoid confusion.

    The second problem with this function is that it allows to update
    resources only of a single RP at a time, even if multiple RPs are
    associated with the same consumer UUID. With introduction of a
    minimum packet rate rule it makes sense to allow to update resources of
    multiple RPs in a single API call. To accommodate this, we need to
    slightly modify arguments this function takes, and embed RP UUID
    in alloc_diff, rather than pass it as a separate parameter.

    Addresses TODO comment from [1].
