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.
