Revert transition to 'service' command
Service doesn't seem to work with plain upstart jobs.

Make sure qemu is stopped before reinstalling/
starting Redeploys currently fail because we're trying to start an already-running
service. Maybe the stop hook doesn't get called on destroy-service? At any
rate, let's just be cautious and make sure the service is stopped before
overwriting the disk image or starting it. - 13. By dann frazier

Use service instead of calling start/stop commands
This is a best practice; but I forget why :)

Avoid read-only issues by using nbd4 instead of nbd0
Once qemu-nbd has attached a file to a /dev/nbdX device read-only, the read-only
setting persists for any other block devices that are attached to it later.
Unfortunately there is no "read-write" flag for qemu-nbd - so that /dev/nbdX
device becomes unusable for anything but read-only devices from then on.
(I'm not sure this is a qemu-nbd bug; it might actually be rooted in the nbd
driver).Since the upstart job uses /dev/nbd0 to extract boot files out of the disk
image, and it does this read-only, the install hook will fail when called
a second time:mount: block device /dev/nbd0p1 is write-protected, mounting read-only
cp: cannot create regular file `/mnt/tmp/tmp.mnt/ usr/bin/ qemu-arm- static'
Read-only file systemThis breaks redeployments. To avoid this, let's use /dev/nbd4. I picked because
nbd0 is used by the upstart job, and nbd[1-3] are used by the image build. - 11. By dann frazier

Clear out any previous deployments
If a user deploys qemu-cloud, destroys the service, then redeploys to the same
system, this will fail with the error:
bzr: ERROR: Already a branch: "make-highbank-ami"We could fix this by checking to see if the directory already exists, running
make clean, then updating the bzr tree. That would prevent us from pulling
a whole new tree. But, it'll probably be more reliable in the long run to avoid
special cases, and just redoing everything we do in a virgin install.Thanks to Robert Ayres for reporting this issue.

Make start/stop scripts set -e
We only run 1 command now, but might do more later
