bug#32779: Cuirass: Crash and unable to restart when an input is unreachable

[Clément Lassieur]

Hi,

Cuirass is unable to recover from this crash, which happens when
'github.com' (which is one of my inputs) is unreachable.

The Shepherd can't restart it (because 'github.com' is still
unreachable) so it disables it.

Fixed in 27f14634102a73d4252d86b912f67e9ad464be1e.  Now it’ll log the
error and keep going.
