Re: Guix deploy --keep-going equivalent for machine connection failures

i'd call it `ignore-connection-failure?`, or if we want to ignore all problems 
for a machine, then `ignore-failure?`.

--keep-going could set the default value for the session, and the machine 
specific variable would override it.

as for the implementation, i'd use continuable exceptions of a specific type, 
and then from scheme code users could install handlers that ignore the 
situation.

avoiding shell scripts these days is a good idea after all.
