Previously, checking if an app was deployed actually checked if there were any running processes. This is not only incorrect, but also fails to take into account applications that do not have running processes and are only used for one-off commands.
This fix migrates apps to the new "deployed" property which is set in core-post-deploy. The result is a slightly faster "deployed" check that is correct and allows non-scaled apps to actually work.
Closes#4398

### Bug Fixes
- #4397: @josegonzalez Correctly handle environment variables in deployment tasks for Cloud Native Buildpacks
- #4394: @josegonzalez Swap order of arguments on config-get call
### New Features
- #4395: @josegonzalez Add environment variable support to CNB-based containers
### Refactors
- #4393: @josegonzalez Use docker-image-labeler in cnb builder-build trigger
### Documentation
- #4396: @nerg4l Invalid link to Herokuish Buildpack Deployment in Cloud Native Buildpacks
### Tests
- #4390: @josegonzalez Run tests faster by not cloning the buildpack each time
### Other
- #4389: @dependabot-preview[bot] chore(deps-dev): bump heroku/heroku-buildpack-php from 188 to 189 in /tests/apps/php
This will allow dropping many of the "source config/functions" calls littered over the codebase. Plugin triggers are the way to perform cross-plugin communication :)

```
### Bug Fixes
- #4388: @josegonzalez Do not inject max-size option when not using local or json-file log-drivers
- #4386: @josegonzalez Update to docker-image-labeler that handles in-use images
### New Features
- #4387: @josegonzalez Only warn if the vector container is stopped when fetching logs
- #4372: @josegonzalez Add ability to clear an individual resource
- #4384: @josegonzalez Add support for injected cron entries from external plugins
### Refactors
- #4373: @josegonzalez Do not attempt to extract Procfile in ps:scale
### Documentation
- #4377: @josegonzalez Add note about the dokku user cron being overwritten by Dokku
### Other
- #3757: @pickettd Add provision line to Windows Vagrant box for dokku-installer
This allows alternative plugins - such as dokku-letsencrypt - to inject scheduled cron tasks into the cron system used by Dokku. Cron systems can choose to include or not include a cron task based on the specified scheduler, and can also optionally use a third parameter to store arbitrary information.

This change minimizes the work needed to be done when tagging images. It edits the image manifest directly only when necessary, allowing restarts of an app to avoid having an extra layer.
This also additionally allows to deploy images with ONBUILD directives without running the ONBUILD directives.
Lastly, users building docker images that run Dokku will need to use a new sudoer wrapper for the `docker-image-labeler` binary to work correctly. A reference version has been placed in the `docker` skeleton directory.
Closes#3931
Refs #4226
The previous lever for manipulating this was the DOKKU_IMAGE environment variable. While this is all well and good, it only works for CNB and is yet another `DOKKU_*` environment variable that need not exist.
While this does not add support for manipulating the CNB stack just yet, the groundwork is set for the future.
Closes#4306
