Add kas-in-docker invocation script
This shall help to standardize the way how to run kas inside a docker container on a kas file that is locally available. The pattern is - checkout repo with kas file(s) - go to directory where the build output should go into - call "kas-docker build /path/to/kas.yml" As building Isar images both require a specific docker image (that could be changed, though) as well as additional privileges (that needs to be changed in Isar one day), the option "--isar" selects that mode. And because the output of an Isar build generally contains root-owned files, the clean command is added which use docker privileges to clean the build folder, avoiding a "sudo".
