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.

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.

The state engine and preloading is performed before the device gets a
chance to register, while this is desirable for preloaded apps, it
introduces a delay on registration which is known to cause issues since
the VPN is also trying to connect at the same time.
This triggers a simultaneous start of the device engine, the API binder
and the supevisor API to avoid delays.

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
