> This is inspired by [~misha@cloudera.com]'s work on HDFS-11383.
> The key names and key version names are usually the same for a bunch of {{KeyVersion}}
and {{EncryptedKeyVersion}}. We should not create duplicate objects for them.
> This is more important to HDFS-10899, where we try to re-encrypt all files' EDEKs in
a given EZ. Those EDEKs all has the same key name, and mostly using no more than a couple
of key version names.
