c6ff87dbd6 Consider pod image in duplicates strategy 
This increases the specificity of the RemoveDuplicates strategy by
removing pods which not only have the same owner, but who also
must have the same list of container images. This also adds a
parameter, `ExcludeOwnerKinds` to the RemoveDuplicates strategy
which accepts a list of Kinds. If a pod has any of these Kinds as
an owner, that pod is not considered for eviction.

7039b6c8aa Refactor function EvictPod to only return an error 
The EvictPod function previously returned a bool and an error. The
function now only returns an error. Callers can check for failure by
testing if the returned error is not nil. This aligns the EvictPod
function with idiomatic Go best practices.

Also, the function name has been changed from EvictPod to evictPod
because it is not used outside the evictions package.

cff984261e Log an error when EvictPod method returns a non-nil error 
End users should be able to see the detailed error from the EvictPod
method when it fails. Updates all strategies to log the error. The
PodLifeTime strategy already logs this error.

4819ab9c69 Add namespace to pod eviction log messages 
In multi-tenant environments it is useful to know which namespace a pod
was evicted from. Therefore log the namespace when evicting pods.

Also, do not log a nil error when successfully evicting pods.

The new PodLifeTime descheduler strategy can be used to evict pods that
were created more than the configured number of seconds ago.

In the below example pods created more than 24 hours ago will be evicted.
