For download-then-kill strategy, this waits for all changing images on the target
release to be available on device before killing the old services. This
will prevent that multicontainer applications get to a state where some
services of the new release start runnning much before others have been
downloaded.
When adding new services to a multicontainer app, the supervisor will
now wait for other changing services to be downloaded before starting
the new service.
Closes: #1812

This removes the need for the app module to know about the naming
conventions for networks and volumes since those exist now within the
service itself. This also fixes a small bug where the volume would be
removed before the service itself had been successfully stopped.

We just added support for the TX2 NX, which supports u-boot
thus allows for using custom device-trees. Let's allow
for Jetson TX2 NX and future TX2 NX derived
device types to have device-trees configurable from the dashboard.

The supervisor filters out some network interfaces for mac address

In these cases we want to avoid restarting the same services

PR #1749 introduced a bug when pushing local target state. An update to
the [image name normalization](f1bd4b8d9b/src/lib/docker-utils.ts (L81))
failed to consider the local image name format. This results in mangling
of image names in the database, i.e. the image `ubuntu:latest` is stored
as `/ubuntu:latest`. This causes an exception to be returned by the
dockerode `getImage('/ubuntu:latest').inspect()` call.
This sends the supervisor into a crash loop and is shown on the supervisor
journal logs as
```
getaddrinfo ENOTFOUND images
at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:64:26)
```
Unfortunately if this happens on a user device, since the mangled image
name is already on the database, the easiest way to fix is to remove the
supervisor database and let the supervisor recreate it. Deleting the
database should be side effect free.

Preparing for the new v3 target state, where the supervisor will make environment
dependent ids optional and rely on using general UUIDs and user known identifiers
for comparison. This PR moves forward in that direction by removing some of those
comparisons for v2 target state.
- imageId to be replaced with imageName
- serviceId to be replace by serviceName
- releaseId to be replaced by commit (future release_uuid)
This is a backwards compatible change, meaning it doesn't completely get rid of
these identifiers (which are still being used by supervisor API and for state
patch), but will not depend on those identifiers for calculating steps to target state.
Change-type: minor
This replaces stored `volatileState` with a more declarative ImageTask API.
An ImageTask stores volatile image state for operations that cannot be
obtained through an engine query, such as fetching and removing an
image, state that can be updated while the task is running.
Image controller methods can now use the `reportEvent` method to create
and update the state of a longer running task.
The image manager module now uses tags instead of docker IDs as the main
way to identify docker images on the engine. That is, if the target
state image has a name `imageName:tag@digest`, the supervisor will always use
the given `imageName` and `tag` (which may be empty) to tag the image on
the engine after fetching. This PR also adds checkups to ensure
consistency is maintained between the database and the engine.
Using tags allows to simplify query and removal operations, since now
removing the image now means removing tags matching the image name.
Before this change the supervisor relied only on information in the
supervisor database, and used that to remove images by docker ID. However, the docker
id is not a reliable identifier, since images retain the same id between
releases or between services in the same release.

This PR cleans up testing for supervisor compose modules. It also fixes broken
tests for application manager and removes a lot of dependencies for those tests
on DB and other unnecessary mocks. There are probably a lot of cases that tests
are missing but this should make writing new tests a lot easier.
This PR also creates a new mock dockerode (mockerode) module that should make it
easier to test operations that interact with the engine. All references
to the old mock-dockerode have not yet been removed but that should come
soon in another PR

- Add tests for network create/remove
- Move compose service tests to test/src/compose and reorganize test descriptions

On HUP, some healthceck services need to complete before
it's safe for the Supervisor to reboot the device when
applying state changes. rollback-{health|altboot}-breadcrumb
are the two files that Supervisor looks for and locks the device
on when present in this patch.
Not closing issue 1459 because there is a possible case where,
on altboot rollback, the breadcrumbs are not present. 1459
may be closed when this edge case is investigated.

A previous PR (#1656) fixed validation for network ipam config,
checking that both network and subnet are defined for each ipam config entry
(as described in the docker documentation).
After that PR, the validations throws an exception if the network target state is incorrect,
but this turns out to be the wrong approach, because that exception is also triggered
when querying target state.
This isn't a problem in normal operation, but it is in local mode, because local
mode queries the old target state before sending a new one. Since the query fails,
the CLI can never push the new target state.
This PR replaces the exception with a warning on the logs, since a
misconfigured network won't cause any engine failures, it will just
prevent containers to communicate through the provided network.
A future improvement should move this validation to an earlier point in the process,
so the target state can get rejected before it even gets to a point it
can be used.
