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.

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

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.

This allows a response to an input with dport=`supevisor api port` and

That way that this is performed is by first adding a depends_on entry
for the target service if it appears in a network mode. Then when we
generate the docker container for this service, we use the containerId
of the target container and replace the network_mode with
`container:<id>`.
When comparing state, we check that the containerId still points to the
contianerId of the target container, and in this way we ensure that
when a network mode target container changes, we change the dependent
container too.

We add a database table, which holds information about the last
timestamp of a log successfully reported to a backend (local or remote).
We then use this value to calculate from which point in time to start
reporting logs from the container. If this is the first time we've seen
a container, we get all logs, and for every log reported we save the
timestamp. If it is not the first time we've seen a container, we
request all logs since the last reported time, ensuring no interruption
of service.

This commit does two related things:
* We make the poll interval a random time between 0.5 and 1.5 times the configured interval.
* We introduce the BALENA_SUPERVISOR_INSTANT_UPDATE_TRIGGER configuration variable, that defaults to true. If this variable is set
to false, then calls to /v1/update are ignored, and on startup the supervisor waits for a poll interval before getting the target state.
This will help especially on cases where there's a large number of devices on a single network. By disabling instant updates and setting a large
poll interval, we can now achieve a sitation where not all devices apply an update at the same time, which can help avoid
overwhelming the network.

Adjacent ports are always grouped together by docker when reporting the
container state (from an inspect), so adjacent ports defined in the
compose file would not match as they would not have been normalized.

it will match the docker output (if it should).
We also don't sort in the fromComposePorts function anymore as that is
handled by the normalize function.
