Running mocha on the coffee and ts sources resulted in unreliable
sourcemaps, and breakpoints not working, among other things. To solve
this, this commit adds package.json tasks which will build both the
coffeescript and typescript files with their sourcemaps and places it
into a build directory. It also copies over other dependent files, such
as test data and migrations.
Another task adds a mocha debugging command, which can be connected to
using a node debugger.
Another tasks runs mocha without a debugging interface, but also without
running linters etc first. This enables the tests to be run much faster.

Resin’s delta server supports Balena deltas as version 3 deltas. This commit adds support for triggering delta generation for Balena deltas, and applying them locally to the device via a simple pull.
The delta version to use when updating has been abstracted away as an env var that is user-defined. The default value is still instructing use of rsync deltas (v2).

We add a bunch of additional unit tests, and also a coverage report using istanbul.
The tests are not meant to cover everything, but they're a first attempt at having *some* unit testing
on the supervisor. There's much to improve but hopefully it helps catch obvious errors.

* Fix healthcheck, stop_grace_period and mem_limit
* Lint and reduce some cyclomatic complexities
* Namespace volumes and networks by appId, switch default network name to 'default', fix dependencies in networks and volumes, fix duplicated kill steps, fix fat arrow on provisioning
* Check that supervisor network is okay every time we're applying target state

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)

Turned out that disk I/O can be the bottleneck when applying deltas on some devices. When the disk can’t keep up and consume the downloaded delta, there’s memory bloat due to buffering.
The updated version provides far better reliability when the device is under load and pretty much constant memory consumption with any number of concurrent deltas.

We've been using UglifyJS 0.4.6 (the webpack default) so far, but this doesn't support ES6 and some dependency
updates are starting to cause builds to break (e.g. https://github.com/request/request/issues/2772, which also happens to break
my builds in the multicontainer branch).
Here we switch to the latest uglifyjs-webpack-plugin which is designed for ES2015 support.

Applying a delta update consists of two parts:
1. The request to the delta server for the delta payload (an rsync batch file, plus some prepended Docker metadata). The response is a redirect to a URL that contains the delta (currently S3).
2. The request for the actual download of the delta. The response is streamed directly to rsync, which applies it onto the mounted root filesystem of the final image.
The first step may take a while as it may trigger the generation of the delta if the request is the first one for this combination of src/dest image and the images are large. If the request times out, either because of the delta server taking too long to respond or bad network, the Supervisor automatically schedules a retry to be performed after a while.
Currently, similar behaviour applies to the second step as well -- if the request fails, we immediately bail out and the Supervisor schedules a retry of the whole process (i.e. from step 1). But in this case it means we might have downloaded and applied some or most of the delta when a socket timeout occurs causing us to start all over again, wasting time and bandwidth.
This commit splits the process into the two discreet steps and improves the behaviour on the second step. Specifically:
- makes the Supervisor try to resume the delta download request several times before it bails out and starts the process all over again.
- removes arbitrary timeout which applied over the whole process and meant some deltas would never manage to be applied (because of large delta size and low network bandwidth).
- makes sure any launched rsync processes always exit and any opened streams consumed and closed.
Most of the improvements are in the two dependencies linked below -- `resumable-request` and `node-docker-delta` -- and this commit merely combines the updated versions of these modules.

Resin OS 2.X removes the use of compressed modules, which was the initial
motivation for us to bind mount kmod into user containers (as Debian distros
don't include support for compressed modules).
This is a breaking change, but we still keep bind mounting on devices that are
on 1.X to ensure we don't break apps currently relying on the feature.
Implementation note: some functions in device.coffee have been refactored to
extract (DRY) a memoization procedure for Promise-returning functions.
`device.getOSVersion()` now also memoizes its result.
