For now, we disable reloading upstart jobs due to bug 1124384. At some point in the future, we could enable it again when that bug is fixed. The change here allows for a boothook in a multipart input to write the file '/run/cloud-init-upstart-reload' and then have configuration reloaded.

# we will not do that. However, I'd like to be able to easily

# test to see if this bug is still present in an image with
|
|
# a newer upstart. So, a boot hook could easiliy write this file.
