From: Michael Opdenacker <michael.opdenacker@bootlin.com>

New oe-selftest and associated "testimage" test to check that generated
package feeds can be used to update the latest image built
by the Yocto Project autobuilder.

Currently, only the "core-image-full-cmdline" image with IPK packages
and the "poky-altcfg" distro is supported.

Test it by running:
oe-selftest -r image_upgrade

Tested on the latest master against yocto-5.0_M3

Interested in your feedback about which settings (such as IMAGE)
can be hardcoded in the scripts or provided by the calling environment.
