This fixes#243 with following changes:
+ Optimize to fetch Pod from k8s client
+ Change to use cache always in DEL.
+ If failed to fetch the pod info from k8s clinet in deletion,
use cached delegates as emergency bailout
+ Add test cases for cache
Crash happens in code line `conf.Delegates[0] = delegate` in function TryLoadPodDelegates,
because len(conf.Delegates) is 0.
