With CRI, kubelet no longer sets up networking for the pods. The dockershim package is the rightful owner and the only user of the newtork package. This change moves the package into dockershim to make the distinction obvious, and untangles the codebase. The`network/dns`is kept in the original package since it is only used by kubelet.
