Zuul was designed to block local code execution in untrusted
environments to not only rely on bwrap to contain a job. This got
broken since the creation of a command plugin that injects the
zuul_job_id which is required for log streaming. However this plugin
doesn't do a check if the task is a localhost task. Further it is
required in trusted and untrusted environments due to log
streaming. Thus we need to fork this plugin and restrict the variant
that is used in untrusted environments.
We do this by moving actiongeneral/command.py back to action/*. We
further introduce a new catecory actiontrusted which gets the
unrestricted version of this plugin.
