Add ssh_enroll module

[Vogtinator]

TODO:

• Depends on #113
• ~There's no cleanup if d exits~
• ~Deselecting all keys does not fully work~

[lnussel]

this is pretty cool, maybe we can have it standalone?

Thought about that as well. It would either have to be integratable into jeos-firstboot to avoid double maintenance or be small enough to have neglegible overhead.

I'd also like to replace the background process + fifo mess with something simpler.

I was thinking of sharing modules between jeos-firstboot and sdbootutil too. Needs little duplication like d(), the file with the actual dialogs can then be sourced by different entry points.

Displaying the randomart is a bit much but not as bad as I thought:

Next I'll make it more clear that the message on the client is important. As @lnussel requested, I'll also try to make this a standalone ssh-pairing script and move it into https://github.com/Vogtinator/ssh-pairing and integrate it into jeos-firstboot that way. Should only require minimal code changes.

Done! Superseded by #116
