Connect worker via RPN to download.kiwix.org

[kelson42]

This should definitly speed-up download of data because:

• no competition on bandwith
• More bandwidth in the rpn than on the public interface

Absolutely, although this task is mostly about setting up this network on scaleway and configuring the mirror server to answer on that second IP, probably using another dns entry.

On hotspot side, support for specifying mirror from the command line and rewriting catalog url to use that mirror.

On cardshop itself, supporting mirror change via env and passing down that to the creator's command line.

We need a new download.kiwix.org server allowing RPN.

@rgaudin I guess we can close the ticket now?

What was done:

• configured RPNv1 in Scaleway webui (demo supports v2 but download only supports v1)
• enable those second iface in both machines (see bellow)
• ensured both machines could reach each-other
• added hosts in both machines (to ease maintenance)
• cardshop creator adds a new host to its container: docker run --add-host download.kiwix.org:10.91.56.88 ...
