Patch 1 to express the idea and for high-level review.
Will add more test cases, and look to see if some of the util methods can be de-dup'ed.

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