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).

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.

Previously it was set at /mnt/root/sys/class/net, which is
the same as /sys/class/net because Supervisor has a network
mode of `host`.

This allows to test that the supervisor build actually runs and opens up the
possibility of running more exhaustive API tests against a working supervisor.

This commit also changes the test:integration command to run integration
tests as different processes. This allows to avoid any test leaking into
each-other because of the use of singletons. This however has the side
effect of tests being slower, but that is a forcing function to refactor
the code.
