To avoid unnecesarilly using resources, we add an exponential backoff
when the noops explicitly come from the device-config module.

During the conversion to typescript, the VPN active check was being
performed on the directory, and not the file that the VPN creates,
meaning it would always return true (as we explicitly create the
directory on startup if it does not exist).

In the case of an airgapped supervisor, with a target state that
requests the vpn be enabled, the supervisor will constantly loop on
trying to set the vpn to on. Unfortunately the vpn requires an internet
connection to be configured, so it will never be turned on.
We add the concept of no-ops to the device-config state change steps,
and don't end the state engine transition while these are present
(similar to how image pulls are implemented).

When using the label `io.balena.features.balena-api` the supervisor will inject 2 environment
variables into the container:
- BALENA_API_KEY
- BALENA_API_URL
This allows the container to access the currently associated API using the KEY.

The default value for the delta apply timeout was changed from `''` to
`'0'` (note strings as these are database values) - but if the value
existed in the database already, this would fail validation. We add a
migration which will look explcitily for the failing value and switch it
to the new default.

This reverts commit 338ba4cdd7.
This is to unblock the release of the supervisor version, pending the
fix of the introduction of the race condition currently affecting v2
deltas.

Non-200 errors were causing the watchdog to restart the supervisor,
which in some cases could cause a restart loop. Instead we change the
code to only treat communication failures as an error, and report status
code failures directly.

We were not allowing newlines previously by virtue of the regex not
allowing them. The docker daemon and supervisor handling code both
support them, so we allow them in the parsing code too.

We were validating the input configuration values by coercing them to
the correct type, and then using the initial value to be saved (which
currently is always converted to a string).
We now use the coerced value as the actual value we will store, and more
importantly emit. This means that the config.on('change' ...) calls will
always be properly typed, which before this change was not a guarantee
that we could make.
