This config backend uses ConfigJsonConfigBackend to update
os.power and os.fan subfields under the "os" key, in order
to set power and fan configs. The expected format for os.power
and os.fan settings is:
```
{
os: {
power: {
mode: string
},
fan: {
profile: string
}
}
}
```
There may be other keys in os which are not managed by the Supervisor,
so PowerFanConfig backend doesn't read or write to them. Extra keys in os.power
and os.fan are ignored when getting boot config and removed when setting
boot config.
After this backend writes to config.json, host services os-power-mode
and os-fan-profile pick up the changes, on reboot in the former's case
and at runtime in the latter's case. The changes are applied by the host
services, which the Supervisor does not manage aside from streaming
their service logs to the dashboard.

This updates balena lint to the latest version to enable eslint support
and unblock Typescript updates. This is a huge number of changes as the
linting rules are much more strict now, requiring modifiying most files
in the codebase. This commit also bumps the test dependency `rewire` as
that was interfering with the update of balena-lint
Change-type: patch
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.
Change-type: minor
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.
