Code Issues Proposed changes

tasks: Ensure machinectl quota value is reasonable 

It appears that when setting a limit which is greater than the size
of the underlying filesystem, machinectl does not change the quota at
all. As such, lets calculate the limit based on the /var/lib/machines
mountpoint or any of its parents.
