[yocto] [[AUH] 12/17] upgradehelper.py: Add settings for enable testimage.

[Aníbal Limón]

Testimage feature will provide the ability to run testimage

Also it will run ptest on recipes that support ptest and retrive
the result for store/send to maintainer.

+upgrade-helper.conf also add the following lines to your conf/local.conf

+INHERIT += "testimage"

+Also if you are running in a server without X11 session, you need to start

+$ vncserver :1
+$ export DISPLAY=:1

+If upgrade is succesful testimage/ptest results are generated into
