Issue MESOS-4345: Implement a network-handle manager for net_cls cgroup subsystem
As part of implementing the net_cls cgroup isolator we need a mechanism to manage the minor handles that will 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.
