> Saving namespace and restarting NameNode will remove existing encryption zones

>
> Currently, when users save namespace and restart the NameNode, pre-existing
> encryption zones will be wiped out.
> I could reproduce this on a pseudo-distributed cluster:
> * Create an encryption zone
> * List encryption zones and verify the newly created zone is present
> * Save the namespace
> * Kill and restart the NameNode
> * List the encryption zones and you'll find the encryption zone is missing
> I've attached a test case for {{TestEncryptionZones}} that reproduces this as
> well. Removing the saveNamespace call will get the test to pass.
