This change adds a new builder - builder-cnb - via the 'DOKKU_CNB_EXPERIMENTAL' environment variable. While support for customizing pack builds is not currently implemented and there may be other missing functionality, this initial implementation allows folks to start playing with CNB.
Future releases of Dokku will provide tighter CNB integration and eventually switch to CNB for default building, as well as allow users to better select builders needed for their applications.
All new code for CNB support should be considered experimental and subject to change as the support evolves over time.
Rather than waiting for the next deploy, take advantage of the retire system to retire these containers immediately.
Note that since the retire process happens out of band, the containers may stick around for up to 5 minutes, after which point they will be removed.
Customization of the wait time to retire - currently 60 seconds - is up for future debate. The containers ultimately haven't been useful for debugging, so keeping them around for longer won't help in most cases, and folks can disable the dokku-retire service (or cron) if that is desired.
There are other places in the codebase that currently act on all apps or could benefit from being able to do so. Being able to run `common.RunCommandAgainstAllApps()` and get that for free will be a boon to implementing this functionality elsewhere.
Better would be to separate the release and deploy aspects into distinct triggers - as well as have it release a specific image - but this is a good first pass.
This is necessary for ensuring ssl certificates can be auto-retrieved for apps, and also easing integration into schedulers that use names and process types as part of DNS records.
As well, this fixes an issue where we may potentially have invalid DNS entries when adding apps to custom networks.
