We do support containers that do not specify NetworkInfo, please take a look at 
the diff of https://reviews.apache.org/r/44514/, in `prepare()`, if the 
container does not specify NetworkInfo, then it will not do anything (just a 
no-op) and subsequently `isolate()` will not do anything for this kind of 
container too.

So my idea is, if operator decides to use `network/cni` isolator, then s/he 
must specify CNI network configuration and plugin which should be acceptable 
since CNI isolator needs CNI network configuration and plugin sounds a 
reasonable requirement to me. But for framework, they do not have to launch 
container to join CNI network, if they do not want a container to join any CNI 
networks, then just do not specify NetworkInfo or specify NetworkInfo without 
`name` field, we should definitly support it.
