Attempt to fix race condition in installer tests, especially the
grub1 test.
The latter was failing when running "parted /dev/sda ..." because
/dev/sda didn't exist yet.
The installer now asks the user to set a root password if stdin is a
tty, which doesn't work for an interactive test.

Hopefully fixes failures like:

This shouldn't be necessary, but it might be that the use of unionfs
is interfering with a clean shutdown.
This allows specifying rules for systemd-tmpfiles.
Also, enable systemd-tmpfiles-clean.timer so that stuff is cleaned up
automatically 15 minutes after boot and every day, *if* you have the
appropriate cleanup rules (which we don't have by default).
You can now run a test in the nixos/tests directory directly using
nix-build, e.g.
$ nix-build '<nixos/tests/login.nix>' -A test
This gets rid of having to add the test to nixos/tests/default.nix.
(Of course, you still need to add it to nixos/release.nix if you want
Hydra to run the test.)
Uses standard NixOS user config merging.
Work in progress: The slave config does not actually start the slave agent. This just configures a
jenkins user if required. Bare minimum to enable a nice jenkins SSH slave.
By default the jenkins server is executed under the user "jenkins". Which can be configured using
users.jenkins.* options. If a different user is requested by changing services.jenkins.user then
none of the users.jenkins options apply.
This patch does not include jenkins slave configuration. Some config options will probably change
when this is implemented.
Aspects like the user and environment are typically identical between slave and master. The service
configs are different. The design is for users.jenkins to cover the shared aspects while
services.jenkins and services.jenkins-slave cover the master and slave specific aspects,
respectively.
Another option would be to place everything under services.jenkins and have a config that selects
master vs slave.
