[PATCH v2 5/5] gitlab-ci.yml: Add jobs that run with custom docker-isar image

[Uladzimir Bely <ubely@ilbers.de>]

This adds possibility to select between `kas-isar` image for building
the project and `docker-isar` one.

By default, if variable `IMAGE` is not set in schedule properties, we
continue using `kas-isar`. Specifying `IMAGE = docker-isar` swtiches CI
to `docker-isar` image that has "avocado" and "qemu-system" packages
preinstalled.
