[Kdc-info] prelim draft of kdc information model

[Sam Hartman]

Hi.  I just finished reading the KDC info draft.

This seems like a good start.

I would like to accomplish the following, perhaps at this IETF meeting perhaps later:

1) Understand how we view salt types and salts within this framework

2) Understand what flags we care about.


Before we finish this document we should also think about how it will
interact with Kerberos extensions.
