As the Supervisor is a privileged container, it has access to host /dev, and therefore has access
to boot, data, and state balenaOS partitions. This commit sets up the framework for the following:
- Finds the /dev partition that corresponds to each partition based on partition label
- Mounts the partitions into set mountpoints in the device
- Removes reliance on env vars and mountpoints provided by host's start-balena-supervisor script
- Simplifies host path querying by centralizing these queries through methods in lib/host-utils.ts
This particular changes env vars for and mounts the boot partition.
Since the Supervisor would no longer rely on container `run` arguments provided by a host script,
this change moves Supervisor closer to being able to start itself (Supervisor-as-an-app).

The issue with the original Supervisor implementation of the firewall is that
on Supervisor start, the Supervisor flushes the INPUT chain of the filter table.
This doesn't play well with services that add to the INPUT chain on startup that
may start up before the Supervisor, such as certain NetworkManager connection
profiles. This change only replaces the BALENA-FIREWALL rule in the INPUT chain,
preserving the other rules as well as their order.

We have seen a few times devices with duplicated network names for some
reason. While we don't know the cause the networks get duplicates, this
can be disruptive for updates as trying to create a container referencing a duplicate
network results in a 400 error from the engine.
This commit finds and removes duplicate networks via the state engine,
this means that even if somehow a container could be referencing a
network that has been duplicated later somehow, this will remove the
container first.
While thies doesn't solve the problem of duplicate networks being
created in the first place, it will fix the state of the system to
correct the inconsistency.

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.
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.

The supervisor had to chroot into the host root in order to read the
journal logs. This won't be possible anymore once the supervisor becomes
an app. This commit copies the journalctl binary and necessary libraries
from a debian image into the supervisor image in order to be able to use
the tool on runtime.

This means that dynamic import statements will emit actual `import`
statements rather than being translated to `require`, the benefit being
that we can now import ES modules via dynamic imports

This PR changes the way the supervisor reads and writes files from /mnt/boot. Reads will
now use the [fatrw utility](https://github.com/balena-os/fatrw/) as a way to minimize corruption of
files in the boot partition, and thus preventing possible bricking of the device.
Since this basically changes the way a lot of configurations are read, this work was being blocked because of
the way tests were being done. While there still remain a couple of legacy tests to be migrated, this PR disables
test:legacy tests when running npm run test, as the work on refactoring those tests is in progress (see #2048) and
fatrw integration is of higher priority.

getImagesForCleanup used to query the Engine for the Supervisor
image, which is unnecessary given that the Supervisor has access
to constants.supervisorImage. Thus, this Engine query is removed.
The method is simplified and made more clear, and
imageManager.isCleanupNeeded doesn't need to be stubbed in tests.

This means that configuration backend tests no longer use stubs and
(mostly) avoid internal dependencies in the tests. Instead of stubs and
mock-fs, the tests use [testfs](https://github.com/balena-io-modules/mocha-pod#working-with-the-filesystem)
which allows working with a real filesystem and ensuring everything is
re-set between tests.
This is the last change needed in order to be able to merge #1971. Here is the list of changes
- [x] Migrate splash image backend tests
- [x] Migrate extlinux backend tests
- [x] Migrate config.txt backend tests
- [x] Migrate extra-uenv config tests
- [x] Migrate odmdata config tests
- [x] Migrate config utils tests
- [x] Migrate device-config tests

Also remove system interface check from ensureSupervisorNetwork.
Previously `ensure` was a Bluebird promise which wasn't awaited in
its composition step. This has been here for some time and may contribute
to issues with duplicate networks. The conversion to native Promises
allows `ensure` to be awaited, hopefully reducing instances of duplicate
networks.
Removing the system interface check for /sys/class/net/supervisor0
because it's superfluous given that the Engine creates the interface
with NetworkManager. It also makes testing a lot more difficult to set up
as /sys/class/net isn't a directory that can be written to for emulating
system interface creation / removal.

Use isNotFoundError which converts an error of the default type
`unknown` into NotFoundError if the error is an instance of NotFoundError.
Thrown errors are of type `unknown` by default so we should use methods
with type guards for better type narrowing.

When code that is unit tested is part of a file that imports modules which
depend on the dbus module, this breaks the unit test environment because there
is no system socket set up, as the unit test mocha config doesn't import fixtures.ts.
For example, if we change src/compose/utils to import device-config or api-binder, both
of those modules import lib/dbus which invokes a dbus.getBus call at the root level. This
is problematic for unit testing.
We can get around the root-level dbus.getBus call by initializing dbus only when it's first
needed. The mocked-dbus test setup code can also be removed in favor of legacy mocha
hooks, which makes the dbus stubbing in the legacy test environment more clear.
We can remove these legacy hooks when all the legacy tests are migrated to unit/integration.
