Allow debugging kubelet image pull times

Browse Source 
This PR changes the buckets of the
kubelet_runtime_operation_duration_seconds metric to be
metrics.ExponentialBuckets(.005, 2.5, 14) in order to
allow debugging image pull times. Right now the biggest bucket is 10
seconds, which is an ordinary time frame to pull an image, making the
metric useless for the aforementioned usecase.
