[routing-wg] Community-driven FAQ for RPKI

We put together a Frequently Asked Questions document for the Resource Public Key Infrastructure (RPKI). 

The aim is to provide a comprehensive overview of common questions that network operators and interested parties ask about the technology itself and the deployment of it, along with peer reviewed answers.

To make this truly inclusive, it is available as an open source project on Github, allowing you to fork, do a pull request with an edit or addition, or open an issue in case you have suggestion.

The original content was written by David Monosov, Melchior Aelmans, Job Snijders and myself, along with contributions from network operators around the world.

The Github project is available here:
https://github.com/NLnetLabs/rpki-faq

The contents are automatically published on the NLnet Labs website:
https://nlnetlabs.nl/projects/rpki/faq/

Many thanks to the NLNOG community for getting this off the ground. 

Cheers,

Alex
