4ce334aa49 reload cni network config if has fs change events 
With go RWMutex design, no goroutine should expect to be able to
acquire a read lock until the read lock has been released, if one
goroutine call lock.

The original design is to reload cni network config on every single
Status CRI gRPC call. If one RunPodSandbox request holds read lock
to allocate IP for too long, all other RunPodSandbox/StopPodSandbox
requests will wait for the RunPodSandbox request to release read lock.
And the Status CRI call will fail and kubelet becomes NOTReady.

Reload cni network config at every single Status CRI call is not
necessary and also brings NOTReady situation. To lower the possibility
of NOTReady, CRI will reload cni network config if there is any valid fs
change events from the cni network config dir.

Merge pull request #825 from abhi/cni_config 
Change to keep in sync with latest cni config

263b0b99d0 Change to keep in sync with latest cni config 
This commit contains change to pick the latest cni config
from the configured CNIConfDir.
With this change any changes made to the cni config file will
be picked up on the kubelet's runtime status check call.
Ofcourse this would lead to undefined behavior when the cni config
change is made in parallel during pod creation. However its
reasonable to assume that the operator is aware of the need to
drain the nodes of pods before making cni configuration change.
The behavior is currently not defined in kubernetes. However
I see that similar approach being adopted in the upstream kubernetes
with dockershim. Keeping the behavior consistent for now.
