kubelet: record an event with a clear reason on host port conflict

241df2d3be kubelet: record an event with a clear reason on host port conflict 
Currently, kubelet silently ignores pods that caused host port conflict. This
commit surfaces the error by recording an event.

It also makes sure that kubelet iterates through the pods in the order of the
creation timestamp, which ensures that pods created later are ignored on
conflict.

8649628c6c Make POD container last OOM victim. 
Setting the oom_score_adj of the PID of the POD container to -100 which is less
than the default of 0. This ensures that this PID is the last OOM victim
chosen by the kernel.

Fixes #3067.
