Code review comment for ~jocave/plainbox-provider-checkbox/+git/plainbox-provider-checkbox-parts:stage-package-updates-from-oem-qa

Thanks for initiating this, couple of modifications based on my work on classic:

Please remove:

- fwts (rather use the dedicated part to get an up-to-date version, even the "local" one you wrote)
- zenity

Add:

- iperf
- iperf3

Uncomment:

#- python3-yaml (I needed this one for checkbox-tillamook)
