VyOS builds and HTTPS

For a while some people kept asking why we do not enable HTTPS on the servers with ISOs and repositories. Now we have enabled it, but it turned out it's not all that simple: since APT doesn't support HTTPS by default and the apt-transport-https package is not installed by the bootstrap stage of the live-build process, the dev.packages.vyos.net server is now unusable and image builds are broken.

We are looking for solutions. If you know how to make live-build use apt-transport-https for the boostrap stage, please tell us. If we don't find anything today, we'll try to make HTTPS optional, and if that turns out to be impractical in VestaCP (which we are using for the web frontend server), we'll just disable it there.

Sorry for the inconvenience!
