This fixes an issue where disk space is not recouped after deploys unless 'dokku cleanup' without arguments is called.
Also injects the label-schema labels as necessary.
Refs #4099
Previous versions extracted the values as strings, prefixing the values with `/bin/sh -c '$CMD'` unnecessarily. This caused issues where we would incorrectly overrride these values when an app had a predeploy script.
Closes#3143
