bug#38320: Cuirass: Allow to use authenticated Git repositories as inputs

["Clément Lassieur" <clement@lassieur.org>]

Hi everyone,

Whoo, nice, thank you so much Mathieu!  I'll test everything this
week-end probably, and start working on the (guix git) / Cuirass
counterpart (which is 1% of the work :D).

Indeed :)  Almost there!

As far as I understand, LATEST-REPOSITORY-COMMIT is never called by the
daemon, it downloads stuff first and then calls ADD-TO-STORE.  So both
using the SSH agent or passing a private SSH key should be
straightforward.
