NodeType is used in Storage and Upgrade while NamenodeRole is used in
BackupNode. It does not make sense to pass DATA_NODE to BackupNode and,
similarly, it does not make sense to pass BACKUP/CHECKPOINT to Storage. Thus,
it may be better to keep two enums.
BTW, the enum names do sound confusing. How about renaming NodeType to
StorageType.

Konstantin had expressed his reservation about this change. If most of you feel
this is is a good idea (I feel it is), I can work on this. So post your
comments.

I'm personally in favor of the change. It's certainly not strictly necessary,
but seems like a nice simplification. I don't think the current terminology is
well-known to users, as these are really internal enums within HDFS.

I think this an unnecessary code change, which is induced by unnecessary
attempt to change current terminology.
