[http-state] http-state charter

Much delayed, but I'm now working on creating our charter.  I've included a first draft below; it borrows heavily from the httpbis charter.  Feedback welcomed.  For a sense of what other WG charters look like, they are here:

Description of Working Group:

The HTTP State Management Mechanism (Cookies) was original created
by Netscape Communications in their Netscape cookie specification,
from which a formal specification followed (RFC 2109, RFC 2965).
Due to years of implementation and extension, several ambiguities
have become evident, impairing interoperability and the ability to
easily implement and use HTTP State Management Mechanism.

The working group will refine RFC2965 to:
* Incorporate errata and updates
* Clarify conformance requirements
* Remove known ambiguities where they affect interoperability
* Clarify existing methods of extensibility
* Remove or deprecate those features that are not widely implemented
and also unduly affect interoperability
* Where necessary, add implementation advice
* Document the security properties of HTTP State Management
Mechanism and its associated echanisms for common applications

In doing so, it should consider:
* Implementer experience
* Demonstrated use of HTTP State Management Mechanism
* Impact on existing implementations and deployments

The Working Group's specification deliverables are:
* A document that is suitable to supersede RFC 2965
* A document cataloguing the security properties of HTTP
State Management Mechanism

Goals and Milestones:
TBD
