upstart needs explicit chroot tests

[James Hunt]

Upstart has no explicit tests for running jobs within a chroot environment. Once bug 1075976 and bug 1079358 are resolved, we should add a new autopkgtest which performs atleast the following tests:

- Ensure a job within a chroot is known to Upstart.
- Ensure a job within a chroot can be started.
- Ensure a job within a chroot can be stopped.
- Ensure a job within a chroot can be restarted.
- Ensure initctl within the chroot cannot control or access any system jobs outside the chroot.
- Ensure initctl within the chroot cannot control or access any user jobs outside the chroot.
- Ensure initctl running outside any chroot is unable to access and or manipulate any job within a chroot.
- Ensure that any jobs run from within the chroot log to /var/log/upstart/ *within* the chroot (see bug 1079710).

= "Nice-to-haves" =

- Ensure initctl within the chroot cannot control or access any jobs in *other* chroots.

James, this would seem to be "Triaged", since those two bugs are now Fix Released.
