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.
Unfortunately, Docker does not persist container IPs on boot, so containers may come up with the wrong IP, resulting in proxying to the incorrect app after a server restart. Instead, we should delete the configs and let ps:restore rebuild the proxy config correctly.
Closes#3932
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.
