Contacts in the system address book are updated by the system. It would be neat to see when a contact changed last.

Describe the solution you'd like

Assign a REV prop to the vcard when generated in \OCA\DAV\CardDAV\Converter::createCardFromUser

Ref https://www.rfc-editor.org/rfc/rfc6350.html#section-6.7.4

Research direction

Start at \OCA\DAV\CardDAV\Converter::createCardFromUser, which the issue identifies as the vCard generation entry point, and read the RFC 6350 REV property definition. Done means generated system address-book vCards include a REV value representing when the contact was last modified.
