[SRU] cloud-init should use "nofail" instead of "bootwait"

It seems like the right thing to do is write 'nobootwait' or 'nofail' based on distro.uses_systemd()

Marking as "critical" owing to Azure instance death. Because Azure instances consider ephemeral devices to be ephemeral per-boot, a stop, resized, or fabric restarted instance may not come back if the instance is presented with a new ephemeral device.

Linked branch has been tested.

The verification of the Stable Release Update for cloud-init has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

FTR, there is no reason to make this specific to Ubuntu or systemd -- "nofail" is the defined by util-linux, it's not a systemd specific thing. upstart introduced "nobootwait" some years ago, but it has always been an upstart specific alias for the official "nofail".

apologies for commenting on a resolved bug, but adding another FTR comment: it is my understanding that, contrary to statements above, the upstart-specific "nobootwait" is/was not equivalent to the util-linux defined "nofail." see e.g., https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/610869 for some differences in behavior.
