The wait-for-it script used during tests would setup a timer
that would send SIGUSR2 to the parent process after the timer ends.
Since node was ignoring additional signals, the timer ending would have
no effect after the node process had replaced the start script. However
when node has pid != 1, SIGUSR2 default behavior is to terminate the
process, meaning the tests would fail after 30 seconds.
The script is now updated so the timer is killed once the services are
ready for the tests.
As reported by issue #2100, the supervisor was not correctly reacting to
`SIGTERM` sent by the engine when terminating the process (for instance
before a reboot). This would lead to the supervisor requiring an
additional 10 seconds to terminate (after which the engine will send a
`SIGKILL`).
The reason for this is explained by the following info coming from Node
> Node.js was not designed to run as PID 1 which leads to unexpected behaviour when running inside of Docker. For example, a Node.js process running as PID 1 will not respond to `SIGINT` (`CTRL-C`) and similar signals. [reference](https://github.com/nodejs/docker-node/blob/main/docs/BestPractices.md#handling-kernel-signals)
On internal testing, it was discovered that simply adding a listener for
the signal on the Node process was enough to handle the signal, even
when the process runs as PID 1.
This adds a listener for `SIGTERM` before starting the supervisor main
loop.
Closes: #2100

The Raspberry Pi config.txt file defines the use of colon to configure
variables of the same name in different ports, for instance on those
devices with two hdmi ports. This syntax was previously not supported by
the supervisor. This change relaxes the syntax validation on config vars
to allow the use of the colon character.

This also adds a 500 response with the old key if the API key
refresh was unsuccessful. Previously, if the key refresh was
unsuccessful, this would result in an UnhandledPromiseRejection.
This is a new interface.
