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
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 sets up the new `test/unit` and `test/integration` folders
and starts classification of some of the test files.
Note that unit tests include, `fs-utils` and `system-info` tests.
While these tests interact with the filesystem, the implementation
of these modules is simple enough, and the tests are fast enough to
allow these tests to fall under the `unit` test category (according to
test/README)
Change-type: patch
We are refactoring the supervisor test suite into unit tests (for
algorithms an domain model tests) and integration
tests (for interaction with out-of-process dependencies).
This means the current test suite needs to be classified into
these two categories, and fixed whenever possible.
This commit moves the test suite under the `test/legacy` folder, this
folder should be progressively migrated and eventually removed.
Subsequent commits will begin to split these files into unit and
integration whenever possible.
