Pagure repo for WG issues

[Paul W. Frields]

I went ahead and imported the old Fedorahosted repo for Workstation WG
issues to Pagure, since FH is being sunsetted soon.  The new repo is
located here:

https://pagure.io/fedora-workstation

The Issues tab contains our old tickets.  These probably need refresh,
but the first step was getting them to a supported app.  When I get a
chance, I'll create a README.md for the repo as well, so it's easier
for people to understand what to do (and not do) with it.
