Review OSLC CM IETF RFC for Configuration-Context header

The OSLC Configuration Management spec requires a new HTTP header, and that requires that we submit an RFC to IETF. The working draft page is a placeholder for a draft of that RFC, for OSLC review before Nick submit it to IETF. The CCM TC have delayed that submission until the Config Mgmt draft is in a more complete state, which is expected over the next 4 weeks or so. There is no OSLC Core 3.0 dependency, just a desire to have the Core TC review and comment on the draft, and that is the purpose of this task.
