Bug 1290620 - Use run-task from decision task; r=dustin This commit does a lot. But it's really not too difficult to comprehend once you focus on the final state, which is basically the same as the "lint" image and derived tasks. Before, the "decision" image contained a "checkout-gecko" script and "run-action" and "run-decision" scripts. The latter 2 invoked the first script. The "run-task" script basically does what the combination of these scripts were doing before. So we switch to it. While we're here, we also replaced the custom Mercurial installation in this image with the shared install-mercurial.sh script. The system-setup.sh script for the decision image is now short and sweet. The YAML files for tasks using this image have been updated to use "run-task." We no longer have to pass an environment variable to hold command arguments. So we revert to putting these arguments inline in the task's command. Dustin never liked passing the arguments as environment variables, so it should make him happy ;) We add --log-no-times because "run-task" prefixes its own timestamps on output lines. The path to the Gecko checkout has been changed from /home/worker/workspace to /home/worker/checkouts to match changes made in bug 1289643. Finally, since "checkout-gecko-and-run" is no longer used, we delete it. The Docker image version has been bumped accordingly. MozReview-Commit-ID: HAGuCz6668Q

Bug 1290620 - Implement a run-task wrapper script; r=dustin Before, we simply executed scripts inside Docker containers. This frequently resulted in a wall of text with command output. It was difficult to discern things like the time spent performing certain actions. Before, individual tasks had to drop permissions from the default root user themselves. Dropping permissions isn't exactly a trivial thing to do and a number of tasks didn't do it or did it wrong. Before, we had a "checkout-gecko-and-run" script that kinda/sorta did common activities for us. But it was written as a shell script and doing advanced things was difficult. This commit can be treated as a rewrite of "checkout-gecko-and-run" as a Python script. But it also does a bit more. It prefixes output with timestamps so we know how long operations took. It features more robust argument parsing, so we can add new features more easily. To prove the new wrapper script works, the lint image and all tasks using it have been converted to use it.
