Leverage async for devscripts role feedback

Long running tasks such as the deploy will now have:
- a timeout via async
- display a feedback while still running

The timeout is needed since, under some circumstances, devscripts itself
doesn't seem to timeout, leading to never-ending run.

The deploy will show an ASYNC POLL every 30 seconds, while the cleaning
will show the message every 10 seconds.
The "timeout" for the deployment is set to 2h by default.
