Qa automatic test 1

Description

In December 2020, January & february 2021 I (@vincent) worked on a POC to get a way to run automatic test. Every details can be found in Qualification project's wiki

This MR is about integrating BlissLauncher's test APK into build system in order to have a build which could be automatically flashed on a real device, (through tradefederation tool) then perform automatic testing.

Considering that:

• It has been done 1 years ago and still not validated
• Bliss launcher test APK is totally outdated
• We didn't go further in test stations dev

We must say if we want to integrate this or if we can close this MR ?
