Create apertis-lava Jenkins configuration

Create a YAML file based on apertis-debos.yaml for apertis lava artifacts. Those artifacts are generated from apertis packages using debos. They are used in the lava initial phase, consisting of booting over nfs, and flashing the rootfs on disk. This job currently is triggered daily. The amount of artifact generated is 150Mb per platform.
