test: command keys

[sapk]

Investigating the keys command (to use it in docker to replace the authorized_keys file), I wrote some tests that could be useful to keep to ensure that the command is working well.

I thought we were going to migrate to the internal SSH on docker because that's the only way to get rootless docker?

I will maybe propose a PR in this direction and see what happen 😄
