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)

Two cases could've caused deadlocks:
1) Two services use a volume, and one service depends on the other. The volume config changes, but we can't update the volume because we need to kill
both services, and yet we can't kill the dependent service because its dependency isn't ready either.
2) A service with handover strategy uses a volume. The volume config changes. We can't update the volume because the running service is using it, and we can't
start the handover because it depends on the volume being ready. So we need to kill the service to update the volume config.
(Same for networks as with volumes)

This module provisions the device and takes care of getting the target state from the API, calling deviceState to apply it.
It also reports the current state of the device back to the API.
An important change is that the initial values of the device configuration (e.g. config.txt) are reported to the API, creating new config
variables if no values exist for a particular key. This will allow better management of config.txt by giving visibility to the initial configuration.
Changelog-Entry: Remove support for keeping the provisioning apiKey on Resin OS 1.X. Report initial values from config.txt and other device configuration variables to the Resin API.

This will be quickly replaced by a newer version with a different API, but for now we needed to maintain backwards compatibility (see #508).
This proxyvisor handles dependent apps and devices with a multicontainer parent app.
It also switches to the new update mechanism by inferring and applying updates step by step.

This commit adds models to manage services, images, volumes and networks.
The main model for this is ServiceManager, which manages the collection of services on the device. It has functions to query what services are running, and to perform actions like starting, killing or performing handovers.
The Service model allows defining the transformations between a container and its service representation, and includes the functions to compare a running service with a target to determine if an update needs to happen.
This model includes the relevant compose file entries for a service that are supported. Bind mounts are disallowed except for the ones that relate to supervisor features, and persistent data is now stored in named volumes.
The Images model allows fetching and removing images, and includes functionality to determine images that have to be cleaned up - now only dangling and old supervisor images are cleaned up automatically, and ApplicationManager
will remove images that correspond to old services that are no longer needed.
The Networks and Volumes models allow managing named networks and volumes that are part of composed applications.
Changelog-Entry: Remove all bind mounts that were specific to 1.X devices. Move the resin-kill-me file for the handover strategy to /tmp/resin. Add environment variables for the location of resin-kill-me and the lockfile. Use running containers to determine what services are running instead of storing them in the internal database. Use named volumes for persistent data.

This update lock library allows an application to take a lockfile in several locations (subdirectories inside a base folder). The user of this library must be able
to exclusively create a lockfile in each of the corresponding locations, and if any of the files exist, the locking fails.

This module takes care of inferring and applying the steps to run multicontainer applications. It will have a Proxyvisor to handle dependent apps and
devices. It understands the relationship between services, networks and volumes to infer the steps in the correct order, also taking update strategies into account.

This model allows modifying config.txt on raspberry pi devices, as well as logging to display, bandwidth control variables and other supervisor
configuration settings. Configuration values are read from the underlying OS and the supervisor configuration where appropriate (i.e. the Config object), instead of storing the current state
in the database. This means that the supervisor will always use the real values to determine if changes have to be made.
This fixes several issues with config.txt, as the current values are now read from the file, and can be reported on the supervisor's first run (which will be implemented in APIBinder).
It also now treats dtoverlay and dtparam values as a JSON array without the enclosing brackets, for instance:
```
RESIN_HOST_CONFIG_dtparam="audio=on","spi=on"
```
Will produce the following lines in config.txt:
```
dtparam=audio=on
dtparam=spi=on
```
Changelog-Entry: Implement inference of device configuration. Allow array values for dtoverlay and dtparam.
