> Several new methods to ClientDatanodeProtocol may need to be added to support querying
version, initiating upgrade, etc.  The admin CLI needs to be added as well. This primary use
case is for rolling upgrade, but this can be used for preparing for a graceful restart of
a data node for any reasons.
