[IPP] Moving "client-info-col" forward

Smith,

I'm generally +1 on this.  Obviously we need to have a discussion of the privacy implications in the Security Considerations section.  And I'd like to make this RECOMMENDED or CONDITIONALLY REQUIRED to support (not the current REQUIRED) with an explicit mention that Clients MUST obtain explicit consent to send the information.  In short, it needs to be aligned with the work we've done in Job Accounting and Job Extensions 2.0.

A quick note below...

I think we also need to explicitly allow non-registered reverse-DNS identifiers since that is what macOS/iOS bundle identifiers and Java class naming uses, with a note about that.  The goal should be to have a stable identifier that you don't have to do fuzzy matching on (like happens with User-Agent in the HTTP world).
