Newer BalenaOS releases have replaced OS variants for a developmentMode
configuration setting. This commit uses this variable to set the OS
variant in the absence of `VARIANT_ID` from the os-release file.

Add a `developmentMode` configuration variable to the schema. Do not expose
this on the device target state until local key-based authentication is
sorted.

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.

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.

The previous module was using `rewire` to get the knex instance from the
db module but that was leading to issues when running tests using `test:fast`.
This provides a fix for the test module that just removes the destroy
call entirely (it turns out it is not necessary).

This functionality is needed when breadcrumbs aren't deleted after a HUP
rollback for whatever reason. Also rename HUP lock function.

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
List of squashed commits:
- Add tests for network create/remove
- Move compose service tests to test/src/compose and reorganize test descriptions
- Add support for image creation to mockerode
- Add additional tests for compose volumes
- Update mockerode so unimplemented fake methods throw. This is to ensure
tests using mockerode fail if an unimplemented method is used
- Update tests for volume-manager with mockerode
- Update tests for compose/images
- Simplify tests using mockerode
- Clean up compose/app tests
- Create application manager tests

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.

This fixes a specific issue when the supervisor cannot find the right
source for deltas (e.g. after the DB gets deleted), where legacy
behavior was to look for any image in the app.
