Different options get applied to each depending on what is needed for the role.
This also updates how we initialize the cluster to better support how metrics exposure and cross-server networking.
This utilizes a Kubernetes Job to start a pod in order to take advantage of completed Job cleanup in Kubernetes. It also properly handles interactivity by ensuring the container has a TTY.
Note that there is currently no provision for parsing docker arguments and translating them into their Kubernetes equivalents.
While this might not seem super intuitive, the key is mostly related to git management, not the ssh-keys we currently use to add/remove access to push to dokku.
Building/testing for ARM does not happen often - the only runtime environment is Raspberry PI, which supports ARM64 - and complicates support for a ton of features. Aside from that, CI runs are much longer for ARM Dokku images, often reaching 15-20 minutes or just timing out completely.
Rather than support an architecture that doesn't have much usage by maintainers and has a lot of maintenance burden, we're removing the platform.
This change converts existing CHECKS files into a healthchecks key that is understood by 'docker-container-healthchecker'. This tool supports a number of different types of container healthchecks - command, http, uptime - and can perform healthchecks against non-web processes.
The use of the old CHECKS file is now deprecated, and will be removed in the next minor version. Users can use the 'docker-container-healthchecker' to convert existing CHECKS files to the new format automatically.
Closes#2760
This makes deploys faster for any that are built from source as the image artifact isn't involved in those cases while also unifying how the file is handled.

Exposing all config values will allow users to skip setting environment variables twice - once as a docker option and once as an env var. Docker will automatically pull the value from the environment if none is set for the --build-arg flag.
Users will still be required to specify each desired env var via --build-arg as otherwise docker builds will complain about unused build arguments.
