--------------------------------

    Attachment: HADOOP-9421.patch

The IpSerializationType change is orthogonal to this patch, so I'd like to defer to another jira if that's ok?

I changed the authMethod in the connection header to specify the authentication protocol - in this case none, or sasl, to allow for future protocols.  I think that's what you wanted?  It also let me handle the funky switch to simple in a cleaner fashion.

I did realize that having the mechanism/proto/serverId tuple is insufficient.  Those are really just the fields required to create the SASL server or client, which is independent of what we're actually authenticating.  Ex. It's not right to assume DIGEST-MD5 means token, when perhaps SCRAM would be a better replacement.  So now I'm passing TOKEN/DIGEST-MD5/... so that some happy day in the future, we can configure the mechanisms for different auth types, and the auth types are a step closer to pluggable.
