Convert inline test definition to a repo and enhance
- Include a setup phase to install or configure any packages and use lava-test-raise
- Include a report stage where the log of the docker file shows exactly which devices are going to be active in this run. (It is otherwise hard for admins of the parent instance to know which devices are in Maintenance for lavafed and which need maintenance work separately.)
- Document how to pick out the job ID from the lavafed output and how that can be put into a URL to view the log. Include this as an output message into the docker test job log file before starting the slave.
