[jira] [Created] (MESOS-5412) Support CNI_ARGS

Dan Osborne created MESOS-5412:
----------------------------------

             Summary: Support CNI_ARGS
                 Key: MESOS-5412
                 URL: https://issues.apache.org/jira/browse/MESOS-5412
             Project: Mesos
          Issue Type: Improvement
          Components: containerization
            Reporter: Dan Osborne
             Fix For: 0.29.0


Mesos-CNI should support the [CNI_ARGS](https://github.com/containernetworking/cni/blob/master/SPEC.md#parameters) field.

This would allow CNI plugins to be able to implement advanced networking capabilities without needing modifications to Mesos. Current use case I am facing: Allowing users to specify policy for their CNI plugin. 

I'm proposing the following implementation: Pass a task's [NetworkInfo Labels](https://github.com/apache/mesos/blob/b7e50fe8b20c96cda5546db5f2c2f47bee461edb/include/mesos/mesos.proto#L1732) to the CNI plugin as CNI_ARGS. CNI args are simply key-value pairs split by a '=', e.g. "FOO=BAR;ABC=123", which could be easily generated from the NetworkInfo's key-value labels.
