e4eaad3d24 kubelet/networking: add support for cni ConfigLists, pass hostport parameters 
** reason for this change **
CNI has recently introduced a new configuration list feature. This
allows for plugin chaining. It also supports varied plugin versions.

5389a74388 kubenet: SyncHostports for both running and ready to run pods. 
This fixes the race that happens in rktnetes when pod B invokes
'kubenet.SetUpPod()' before another pod A becomes actually running.

The second 'kubenet.SetUpPod()' call will not pick up the pod A
and thus overwrite the host port iptable rules that breaks pod A.

This PR fixes the case by listing all 'active pods' (all non-exited
pods) instead of only running pods.

902ba4e249 Add network-plugin-mtu option for MTU selection 
MTU selection is difficult, and if there is a transport such as IPSEC in
use may be impossible.  So we allow specification of the MTU with the
network-plugin-mtu flag, and we pass this down into the network
provider.

Currently implemented by kubenet.

Automatic merge from submit-queue

kubenet: Fix host port for rktnetes.

Because rkt pod runs after plugin.SetUpPod() is called, so
getRunningPods() does not return the newly created pod, which
causes the hostport iptable rules to be missing for this new pod.

c83ad19ae9 kubenet: Fix ipv4 validity check 
The length of an IP can be 4 or 16, and even if 16 it can be a valid
ipv4 address. This check is the more-correct way to handle this, and it
also provides more granular error messages.
