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

We don't need to read the host's hostname through /mnt/root/etc/hostname,
because the hostname is written to config.json on a change. When the hostname
has never changed, it won't be found in config.json, so we can default to
the Supervisor container's /etc/hostname as it will match the host's
/etc/hostname, the network mode being `host`.

This commit updates all backends that write to /mnt/boot to do it
through a new `lib/host-utils` module. Writes are now done using write +
sync as rename is not an atomic operation in vfat.
The change also applies for writes through the `/v1/host-config`
endpoint.
Finally this change includes some improvements on tests.

This is required as we are phasing out app ids and we need to be able to
get app uuid from the current state of the network. The app-id now
exists as a container in new networks
This commit will restart containers as it needs to recreate the network.
This change updates types and database format in order to allow
receiving the new format of the target state from the cloud and allow
applications to keep working.
This change also updates metadata in the containers, meaning services
will need to be restarted on supervisor update

This PR cleans up testing for supervisor compose modules. It also fixes broken
tests for application manager and removes a lot of dependencies for those tests
on DB and other unnecessary mocks. There are probably a lot of cases that tests
are missing but this should make writing new tests a lot easier.
This PR also creates a new mock dockerode (mockerode) module that should make it
easier to test operations that interact with the engine. All references
to the old mock-dockerode have not yet been removed but that should come
soon in another PR
List of squashed commits:
- Add tests for network create/remove
- Move compose service tests to test/src/compose and reorganize test descriptions
- Add support for image creation to mockerode
- Add additional tests for compose volumes
- Update mockerode so unimplemented fake methods throw. This is to ensure
tests using mockerode fail if an unimplemented method is used
- Update tests for volume-manager with mockerode
- Update tests for compose/images
- Simplify tests using mockerode
- Clean up compose/app tests
- Create application manager tests

This paves the way for running multiple applications and storing
information related to the application against the application itself. A
couple of hacks have been added to v1 and v2 endpoints to maintain
compatability but these should eventually be removed with the addition
of a v3 api.

In order to make supervisor upgrades more transparent, lets move away
from this env var since it requires a container restart any time the supervisor
is upgraded. We should ultimately move towards providing the supervisors
set of capabilities, but that can come later

This is part of the work to make the application-manager module much
less monolithic, in preperation for system apps and more generally
multi-app.

ConfigJson users now don't need to worry about initialization.
It's done lazily on the first public method call.
Implementation is also rewritten to follow async/await pattern.

That way that this is performed is by first adding a depends_on entry
for the target service if it appears in a network mode. Then when we
generate the docker container for this service, we use the containerId
of the target container and replace the network_mode with
`container:<id>`.
When comparing state, we check that the containerId still points to the
contianerId of the target container, and in this way we ensure that
when a network mode target container changes, we change the dependent
container too.

We change the lockfile to /tmp/balena/updates.lock, and the resin-kill-me file to /tmp/balena/handover-complete.
In the host, we change to use /tmp/balena-supervisor instead of /tmp/resin-supervisor.
We add BALENA_ env vars in addition to the RESIN_ env vars.
We keep backwards compatibility by using both paths for the lockfile and handover, and keeping the RESIN_ env vars.
Changelog-entry: Move the handover and lock files to /tmp/balena, rename them, and add BALENA_ env vars

We add a bunch of additional unit tests, and also a coverage report using istanbul.
The tests are not meant to cover everything, but they're a first attempt at having *some* unit testing
on the supervisor. There's much to improve but hopefully it helps catch obvious errors.
