[dev machines] script for cleaning up temporary taskotron files

[Kamil Paral]

Hello,

if you use libtaskotron in a developer environment (running some taskotron tasks locally
from time to time), there is a new script that will make sure taskotron temporary files
will get cleaned up regularly. Look into conf/tmpfiles.d/ in libtaskotron checkout.

This will probably get handy with the recent addition for task artifacts - you probably
don't want to keep them around permanently on a developer machine.

Cheers,
Kamil
