A read <i>r</i> of a memory location <i>x</i>
holding a value
that is not larger than a machine word must observe
some write <i>w</i> such that <i>r</i> does not happen before <i>w</i>
and there is no write <i>w'</i> such that <i>w</i> happens before <i>w'</i>
and <i>w'</i> happens before <i>r</i>.
That is, each read must observe a value written by a preceding or concurrent write.

    * Note: for this change, the other allocators still exist and are the default.
    * It supports two modes:
        * CIDR range allocations done within the cluster that are then propagated out to the cloud provider.
        * Cloud provider managed IPAM that is then reflected into the cluster.
