for_all_repos: Exit on command failure

KAS should exit with the appropriate exit code, if the command parsed to the for_all_repos
plugin fails to apply on one of the repositories.

Example use-case: This allows for CI pipelines or wrapper scripts to take appropriate action (e.g. fail),
if an issue occured within the KAS for_all_repos command.
