device.getID caused a fatal error when connection was down, as the memoization with `promise: true` throws
synchronously. Changing memoizee to use `promise: 'then'` makes the memoization work as expected.

We add an extra image/container cleanup before applying updates, allowing any unwanted images to be deleted.
When doing this, we take care not to delete images that will be used when the target state is applied.
This prevents the problem of stale images being stored while the update lock is set, potentially
leaving the device out of space.
Running the cleanup *before* applying the update ensures that only one target image is downloaded: if a stale one
had been downloaded previously, it will be deleted before starting the update for the new one. This can have a slight
impact on delta performance, since the delta is potentially done from an older (and more different) version of the app,
but can have a big impact on storage usage, as not doing this would duplicate the required free storage space when
the update lock is set.

The lock is now located at `/tmp/resin-supervisor/<appId>/` on the host, and `/tmp/resin/`
on the user container. The old lock location is supported only in Resin OS 1.X (and both locks are
taken in that case).
This fixes the race condition when the app is started before the supervisor, and takes a lock that is
cleared on supervisor startup.

Local mode makes the API accept unauthenticated requests.
Local mode now also removes app containers when stopping them.
Local mode only works on a host OS that has `VARIANT_ID = "dev"` in /etc/os-release.
Also add more explicit logging when stopping an app and it was already stopped
or the container was already removed.

Up to now we've only been running the "special actions" (like vpn on/off, logs on/off)
when the target state includes a current value for the corresponding config variable.
We now also check if there was a *previous* value, and in that case also call the action function.
These functions are prepared to reset to a default when they're called with an undefined value.

We've been using docker attach, which only gives us the logs since we attach. This change allows getting the
full logs from the beginning.
We also use the timestamps that come with the logs from docker, as they will be more precise and are more relevant now
that we're getting previous logs from history.

On ResinOS 2.X the default mounts should not include the previously deprecated host_run, and there's no connman which makes the connman mount confusing.
This is a breaking change as it is not backwards-compatible on non-ResinOS instances of the supervisor.

The logic for updateStatus.forceNext is changed so that its value is checked when the scheduled update is run, instead
of when the update is scheduled. And when an update is already scheduled and a new request comes in,
we mark forceNext as true if the new request requires a force update.

Current delta timeouts are too limiting, so we increase the request timeout to 30 minutes which is big enough that
the server will time out first and we can provide a nice message letting the user know we'll retry; and we increase
the total timeout to 24 hours to account for really big deltas over slower connections (the rsync calls will time out anyways
if something else goes wrong, as they have a 5 minute I/O timeout).
The timeouts are now configurable with the RESIN_SUPERVISOR_DELTA_REQUEST_TIMEOUT and RESIN_SUPERVISOR_DELTA_TOTAL_TIMEOUT
configuration variables.

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.
