Include duration in logs when evicting pods

Would be nice if the CLM logged for how long it had tried to evict each pod, to make it more clear which pods are not evictable for a long time.

I think it eventually logs how long it took to complete

Line 387 in dc1763e

    
           localLogger.Infof("Pod evicted. (Observed termination period: %s)", time.Now().UTC().Sub(start))

which takes up to

Line 420 in dc1763e

    
           gracePeriod := time.Duration(*pod.Spec.TerminationGracePeriodSeconds)*time.Second + podEvictionHeadroom

I am not sure it makes sense to log the retry progress as that may unnecessary pollute logs.

This is about force eviction (kubernetes delete -> grace period -> pod deletion), I think Mikkel meant the total time.
