enhancement: add the ability to provide collabora fonts from openCloud

[fschade]

Description

This PR introduces an API and web-APP to manage fonts and make them available to collabora.
Please note, collabora does not know about that api until it gets configured with ist, e.g. --o:remote_font_config.url=https://$OC_HOST/fonts/fonts.json.
