As the Supervisor is a privileged container, it has access to host /dev, and therefore has access
to boot, data, and state balenaOS partitions. This commit sets up the framework for the following:
- Finds the /dev partition that corresponds to each partition based on partition label
- Mounts the partitions into set mountpoints in the device
- Removes reliance on env vars and mountpoints provided by host's start-balena-supervisor script
- Simplifies host path querying by centralizing these queries through methods in lib/host-utils.ts
This particular changes env vars for and mounts the boot partition.
Since the Supervisor would no longer rely on container `run` arguments provided by a host script,
this change moves Supervisor closer to being able to start itself (Supervisor-as-an-app).

This reverts commit 00e389e5f5.
Images generated using this dockerfile still don't have the right
architecture. More testing is needed
Change-type: patch
This is necessary since the builder no longer passes the platform flag
to the build. This would lead to dockerfiles that are mixing multi and single
arch stages to pull the wrong architecture images, particularly when
trying to build images in emulated builds (e.g. armv7hf built on aarch64).
Moving the full build to multi-arch solves this as the docker engine is
capable of chosing the right architecture from the manifest.

Change-type: patch
Preloaded devices can require that the device is pinned to the preloaded
release on provisioning. However if the provisioned release gets
released in the future, that would lead to the device remaining in "VPN
only" state forever as the provisioning process could not finish due to
pinning failure.
This commit changes the behavior so if the release does not exist, the
pinning step is skipped and the device follows the fleet pinning state.

Change-type: patch
The issue with the original Supervisor implementation of the firewall is that
on Supervisor start, the Supervisor flushes the INPUT chain of the filter table.
This doesn't play well with services that add to the INPUT chain on startup that
may start up before the Supervisor, such as certain NetworkManager connection
profiles. This change only replaces the BALENA-FIREWALL rule in the INPUT chain,
preserving the other rules as well as their order.

We have seen a few times devices with duplicated network names for some
reason. While we don't know the cause the networks get duplicates, this
can be disruptive for updates as trying to create a container referencing a duplicate
network results in a 400 error from the engine.
This commit finds and removes duplicate networks via the state engine,
this means that even if somehow a container could be referencing a
network that has been duplicated later somehow, this will remove the
container first.
While thies doesn't solve the problem of duplicate networks being
created in the first place, it will fix the state of the system to
correct the inconsistency.

We have seen a few times devices with duplicated network names for some
reason. While we don't know the cause the networks get duplicates,
this is disruptive of updates, as the supervisor usually queries
resource by name, resulting in a 400 error from the engine because of
the ambiguity.
This replaces those queries by name to queries by id. This includes
network removal. If a `removeNetwork` step is generated, the supervisor
opts to remove all instances of the network with the same name as it
cannot easily resolve the ambiguity.
This doesn't solve the problem of ambiguous networks, because even if
networks are referenced by id when creating a container, the engine will
throw an error (see https://github.com/balena-os/balena-supervisor/issues/590#issuecomment-1423557871)

This includes:
- proxyvisor.js
- references in docs
- references device-state, api-binder, compose modules, API
- references in tests
The commit also adds a migration to remove the 4 dependent device tables from the DB.
