Up until now, every project using CI-Tron had to write their own job
submission flow because CI-Tron itself was not providing any official
way of interacting with it via GitLab.
This however changed, and the solution is vastly superior to what we
have been using in Mesa:
* Ability to pass all the environment variables of the job to the DUT,
so no need to remember to add variables in
`export-gitlab-job-env-for-dut.sh` anymore
* No dependency on Mesa code, which means no need to wait on
python-artifacts and the ability to replicate a run by just copying
the job description outputted by the job \o/
* Ability to have as many initrd, HTTP, and TFTP artifacts as wanted
* Ability to expose a variable through a TFTP/HTTP endpoint or as an
initrd
* Ability to overwrite the platform environment (machine-specific FW)
* Ability to have as many kernel cmdline variables, all merged when
generating the final cmdline. This makes it easy to share some
snippets of cmdline between jobs
Transitioning from the custom to the generic template is however pretty
involved. This commit does the minimum changes needed to switch to the
new model, often simply replacing the B2C_ prefix with CI_TRON_.
Further renaming of "b2c" prefixes into "ci-tron" is left for future
commits.
