During first time run of the supervisor, the target state is queried
by `reportInitialEnv`. Since this happens early on the initialization
process, this target state report is missed by any listeners and this
can lead to the initial target state not beeing applied (see #1455).
This PR ensures that target state is re-emitted if there were no
listeners setup on call to update.

Some endpoints filter data based on the scope of the API key
used to make the request. When in LocalMode the check was not
being made correctly and all apps were considered out of scope.

This paves the way for running multiple applications and storing
information related to the application against the application itself. A
couple of hacks have been added to v1 and v2 endpoints to maintain
compatability but these should eventually be removed with the addition
of a v3 api.

Currently, when the label `io.balena.features.balena-socket` is set,
the balena engine socket is mounted under `/run/balena-engine.sock`.
This causes a problem when using systemd inside the container, since
this service remounts `/run` and `/run/lock` as tmpfs, causing the
socket to become unavailable.
Making a mount of the socket into `/host/run` solves this issue. This is
the same approach taken with DBUS.

The memory information reported by the supervisor currently
estimates the value of used memory as `MemTotal - MemFree`.
However, linux systems will try to cache and buffer as much
memory as possible, which will affect the output of `MemFree`
(from /proc/meminfo) and in consequence the memory usage seen
by the user on the dashboard, which will appear much greater than
it is.
The correct calculation should be `MemTotal - MemFree - Buffers - Cached`,
which the calculation performed by `htop` and the `free` commands.

In order to make supervisor upgrades more transparent, lets move away
from this env var since it requires a container restart any time the supervisor
is upgraded. We should ultimately move towards providing the supervisors
set of capabilities, but that can come later

When trying to apply SSDT overlays in Up Board, the supervisor currently
gets stuck in a loop trying to apply target state. See #1465
This was due to a bug in parsing the configuration, which lead to
the method bootConfigChangeRequired returning true when no change was
needed.

Each service, when requesting access to the Supervisor API, will
now get an individual key which can be scoped to specific resources.
In this iteration the default scope will be to the application that
the service belongs to.
We also have a `global` scope which is used by the cloud API when in
managed mode.

Controlled by BALENA_HOST_FIREWALL_MODE, the firewall can
either be 'on' or 'off'.
- In the 'off' state, all traffic is allowed.
- In the 'on' state, only traffic for the core services provided
by Balena is allowed.
