add package gluon-config-mode-contact-info

This is an upstream-package that adds a field to the config-mode page.
We have downstream changes on this packages that redirect the
contact-info into another field in uci.

This way the contact info is not published using respondd but can be
fetched using our contact-pull mechanism.
