When assigning multiple host ports to a single container port before
this change, the supervisor would incorrectly take only the first host
port into consideration. This change makes it so that every host port
per container port is considered.

Prior to this change, we would `_.uniq` the expose value before adding
values from the port mappings. This could cause ports to get added
twice, which would cause the supervisor to think that there is a
configuration mismatch.

Even though this would never have attempted to report the state to the
api during local mode, it leaves behind artifacts which would cause the
state to be sometimes reported when exiting local mode. This would cause
the api to reject the update unecessarily.

Removes default 'example' service definitions that
are included by Avahi 0.7+. These conflict with
our balenaOS advertised services, causing potential
issues.

This had a bug where it was using the `in` operator on a list. It may
have worked for some cases, but would have failed for others.

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.

Container logging is now handled by a class which attaches and emits
information from the container. We add these to the directory
logging-backends/, and rename it to logging/.

We also add a catch to any errors when getting configuration, and send 503 in this case, even if it's
unlikely.

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.

When comparing a stopped container after a start request, the container
ID will be present in the target state (where usually it is not). We
were already filtering this value out of the current state, but
neglected to do so for the target state. This change now ensures we
remove it from both alias lists if it exists.

In an edge case observed in the field, a supervisor's database held two applications
because the device had been moved and the update lock was set in the old app. This causes
the updated supervisor to be unable to start, logging "No compatible releases found in API",
because it can't fetch the release for the app it was moved from.
This commit changes the migration code to iterate through all apps, and remove any for which
we can't get a release.

If the kernel was built with support for ip6tables, there's no need to load the module. This is the case when running
balenaOS in a container in Mac OS, which also can't do modprobes easily.
