Yu-Ju Hong ab5e0e0b5c Use the full hostname for mirror pod name. 
This change appends the full hostname to the mirror pod name (instead of taking
the first token) so that if the hostname is overriden, we'd not be creating
unncessary name conflicts. An example would be that a user overrides the
hostnames to be "127.0.0.1" and "127.0.0.2", and both of them were resolved to
"127" for the mirror pod name suffix.

Also, because `uname -n` could return a FQDN or not, this change takes only
the first token of it as the hostname for consistency.

Yu-Ju Hong c075719f05 Kubelet: fix the runtime cache to not cache the stale pods 
If a pod worker sees stale pods from the runtime cache which were retrieved
before their last sync finished, it may think that the pod were not started
correctly, and attemp to fix that by killing/restarting containers.
There are two issues that may cause runtime cache to store stale pods:
  1. The timstamp is recorded *after* getting the pods from the container
     runtime. This may lead the consumer to think the pods are newer than they
     actually are.
  2. The cache updates are triggered by many goroutines (pod workers, and the
     updating thread). There is no mechanism to enforece that the cache would
     only be updated to newer pods.

This change fixes the above two issues by making sure one always record the
timestamp before getting pods from the container runtime, and updates the
cached pods only if the timestamp is newer.

Rohit Jnagal 1511dbf0b5 Expose pod name as a label on containers. 
Full pod name is exposed under key 'kubernetes.io/pod'.
It helps in introspection by looking at all containers in a pod through
docker ps -a -f label=kubernetes.io/pod=podXXX

We also plan to visualize this in cAdvisor.
