> As part of implementing the net_cls cgroup isolator we need a mechanism to manage the minor handles that will be allocated to containers when they are associated with a net_cls cgroup. The network-handle manager needs to provide the following functionality:
> a) During normal operation keep track of the free and allocated network handles. There can be a total of 64K such network handles.
> b) On startup, learn the allocated network handle by walking the net_cls cgroup tree for mesos and build a map of free network handles available to the agent.
