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 includes:
- proxyvisor.js
- references in docs
- references device-state, api-binder, compose modules, API
- references in tests
The commit also adds a migration to remove the 4 dependent device tables from the DB.

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.

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 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

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 excludes route tests or refactoring. Also, created tests
for API middleware.

Merged docker-utils and delta tests into a single test suite. They are
now ran as part of the integration tests using the real engine.
Change-type: patch
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.

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.
Update-lock tests now use the actual filesystem for testing, instead of
relying on stubs and spies.
This commit also fixes a small bug with update-lock that would cause a
`PromiseRejectionHandledWarning` when the lock callback would throw.
Now the tests are ran against the actual docker engine instead of
against mockerode.
The new tests actually caught a bug in
`volumeManager.removeOrphanedVolumes`, where that function would try to
remove volumes for stopped containers, causing an exception.
This commit also fixes that bug.
This also needs to modify the test environment as database migrations
will look for `config.json` in the location given by the variable
`CONFIG_MOUNT_POINT`.
The volume tests now run against the actual docker engine setup via dind

The supervisor used to rely on specific event reporting for identifying
issues at runtime. As the platform has grown, it has become much more
difficult to get any signal from the event noise. Recently the API side
for these events has been disabled, meaning these events only
contribute to bandwidth consumption. This commit disables the
event reporting feature of the supervisor which will be most likely
replaced by something like Sentry in the near future.

`withDefault` is a type helper that allows to create a type that
defaults to a default value when trying to decode a nullish value.
That type was not correctly working with boolean types, causing `false`
values to be replaced by true. This would specifically cause issues when
parsing the target state, where a `running: false` in a service would
become a `running: true` due to the type decoding.
Change-type: patch
The supervisor uses the following pattern for async module
initialization
```typescript
// module.ts
export const initialised = (async () => {
// do some async initialization
})();
// somewhere else
import * as module from 'module';
async function setup() {
await module.initialise;
}
```
The above pattern means that whenever the module is imported, the
initialisation procedure will be ran, which is an anti-pattern.
This converts any instance of this pattern into a function
```typescript
export const initialised = _.once(async () => {
// do some async initialization
});
```
And anywhere else on the code it replaces the call with a
```typescript
await module.initialised();
```
