             Summary: Implement a network-handle manager for net_cls cgroup 
subsystem
                 Key: MESOS-4345
                 URL: https://issues.apache.org/jira/browse/MESOS-4345
             Project: Mesos
          Issue Type: Task
          Components: containerization
            Reporter: Avinash Sridharan
            Assignee: Avinash Sridharan


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.
