When updating from old supervisors (<7.0.0), we've been so far using a fake id 1 for serviceId, imageId
and releaseId since these were not available in the old supervisor. This causes problems when the supervisor
tries to report these values to the API. Moreover, the app from the legacy supervisor has an image URL
that doesn't include the content hash - this causes the supervisor to believe the image is not really downloaded
and try to fetch it again.
To fix these issues, we add a request to the API when the supervisor starts up and detects that there's a legacy
app that needs to be normalised. We fetch the appropriate release, and use it to populate the resource ids
and the updated image URL.
This should avoid the unnecessary image download, and errors reporting target state after an update.

This avoids issues on provisioning where the current state
(esp. config.txt) that we want to save is retrieved without
a RESIN_ or BALENA_ prefix, causing those values to be lost.

i.e. if we're not provisioned or if the target state is empty (of apps), then we
read apps.json to preload. We then mark that the target state has been set to avoid
trying to preload again if we ever get an empty target state from the API.

They will take precedence over any existing RESIN_ variables. We strip both namespaces now
whenever we get the target values.
This also fixes preloading with a legacy config (the interface to get the config keys from
the legacy apps.json was broken).

The resinApiEndpoint config option existed for legacy reasons, where the
apiEndpoint was passed in via env vars, but this is no longer the case,
and the current supervisor wouldn't run on these older versions of
resinOS anymore anyway, so I've removed the references to this legacy
endpoint, as it made reasoning about offline mode weird.

The supervisor will now check that a source of an application matches
the current source, and only start it if so.

Also includes various improvements and bugfixes to services and the migration from legacy /data to volumes.
The switch ti migrations involves a dirty hack for webpack to properly resolve the paths to the migrations js files - it uses an expression
that webpack can't resolve, so we hardcode it to a value and use the ContextReplacementPlugin to make that value resolve to the migrations folder.
The downsides to this approach are:
- a change in knex code would break this
- the migration code is added twice to the supervisor image: once in the migrations folder (because knex needs to loop through the directory to find the files),
and once inside app.js (because I can't make webpack treat them as external)

This module will take care of applying the target state for the device and reporting its current state.
The state itself is handled by two other modules, ApplicationManager and DeviceConfig. The former will take care of running applications (including the dependent ones
via its Proxyvisor), and the latter will take care of device configuration like config.txt and supervisor configuration variables.
The way state is applied differs radically from the previous approach: the old application.coffee had a big `update` function that took all of the steps from fetching the target state
to running the containers. DeviceState, instead, does an iterative process through `triggerApplyTarget` of inferring the next steps to perform towards the target state, by looking at the current state and asking the ApplicationManager and DeviceConfig for
the next steps. It then applies the next steps and every time a step is completed, it schedules another round of inferring and applying the next steps.
Special care is taken to ensure `applyTarget` is not called simultaneously more than once.
This commit also adds a "device" module to handle reboot and shutdown, and moves gosuper calls to a separate module.
The module also uses a "network" module to manage network-related parts of the device's current state: IP addresses and the connectivity check.
The module implements a "normaliseLegacy" function that allows a migration from the models from older versions of the supervisor to the multicontainer models,
so that in case of a supervisor update we can have minimal downtime and bandwidth consumption when updating to the multicontainer supervisor - this migration allows
us to avoid cleaning up images, and also allows migrating the contents of the old /data for the app.
