[OE-Core][PATCH 0/4] testimage: add failed test post actions and fetch more data

["Alexis Lothoré" <alexis.lothore@bootlin.com>]

Hello,
this small series is related to some disk space issue observed by the SWAT
team (see [1]) which eventually leads to tests failure. In order to help
diagnose those issues, I propose to enrich the retrieved artifacts with
some additional data, like disk usage on target and on host (in case the
target is a virtualized guest)

To do so, this series first reworks a bit actions executed on failed tests
to allow declaring a sequence of actions. It then introduces two small
actions which basically run "df" on target and host. I chose to store
those stats in dedicated files, thinking it is better than "contaminating"
tests steps logs with those very specific data.
