Taskcluster

GENERAL

▶ [minor]
Add a docker-worker capability `disableSeccomp` to disable the seccomp
system call filter.

It allows significant information leakage, and its use should not be
considered secure. This is required to run `rr` inside a container, as
described here: https://github.com/mozilla/rr/wiki/Docker

▶ [patch]
Adjust GCP CloudBuild config to cancel other ongoing jobs, so that the latest job is the only one that runs and no race conditions will occur with deploying to dev.

▶ [patch]
Upgrade many deps with the following command:
`pmac add 5692 5691 5690 5689 5688 5687`

▶ [patch]
Upgrades to latest Node version, v16.17.1, which is a security release.

USERS

▶ [minor]

WORKER-DEPLOYERS

▶ [patch] [5666](https://github.com/taskcluster/taskcluster/issues/5666)
The generic-worker no longer panics if it gets no HTTP responses from Queue for over 15 minutes.

DEVELOPERS

▶ [minor]
Refactored github status checks handler to do handle task status transitions in single place.

Previous implementation relied on two handlers: taskDefined and statusChanged.
For some tasks both events happened at the same time, which led to a race condition and multiple check_runs being created.
To prevent concurrent handlers overwriting newer updates, simple time-based check was added to prevent this.
