Clayton Coleman 9efd40d72a kubelet: Preserve reason/message when phase changes ...

The Kubelet always clears reason and message in generateAPIPodStatus
even when the phase is unchanged. It is reasonable that we preserve
the previous values when the phase does not change, and clear it
when the phase does change.

When a pod is evicted, this ensurse that the eviction message and
reason are propagated even in the face of subsequent updates. It also
preserves the message and reason if components beyond the Kubelet
choose to set that value.

To preserve the value we need to know the old phase, which requires
a change to convertStatusToAPIStatus so that both methods have
access to it.
