Upstream-Issue: NixOS/nix#10136

Describe the bug

Perform an 'administrative' shutdown of a Nix remote builder at runtime via stopping its nix-daemon and preventing its socket to reactivate it, if you think this is a feature request for 'administrative' shutdown features, feel free to relabel it.

The remote builder should not be usable anymore as it has no running nix-daemon, run a nix build on anything that registered it as a remote builder, observe that everything is failing with:

error: cannot connect to socket at '/nix/var/nix/daemon-socket/socket': Connection refused

and crashing the whole build instead of switching to the next remote builder.

Steps To Reproduce

systemctl stop nix-daemon && systemctl stop nix-daemon.socket
nix-build anything that will schedule it on that remote builder.
See error

Expected behavior

Graceful failover to the next remote builder or local building.

nix-env --version output

2.18.1.
