------------------------------------------------------------
Patch 3 to address all other comments from [~shahrs87].
Also moved more static functions to {{KMSUtil}}, and added checks for nullity
on the params - I think it makes sense to do the additional check now that it's
moved to util. Existing behaviors of these methods are otherwise not changed.

> HADOOP-13827 already enabled the KMS to re-encrypt a {{EncryptedKeyVersion}}.
> As the performance results of HDFS-10899 turns out, communication overhead
> with the KMS occupies the majority of the time. So this jira proposes to add
> a batched interface to re-encrypt multiple EDEKs in 1 call.
