This standardization makes it somewhat easier to read stacktraces as the command names are all uniform, so it will be slightly easier to scan trace output.
While I do not agree with _every_ style change, this will force Dokku to have consistent formatting across all shell scripts, which is arguably a Good Thing™.
The command used to reprocess everything is:
```shell
shfmt -l -bn -ci -i 2 -w .
```
Some systems - such as a mounted read-only CIFS filesystem - do not fully support chown, and chowning should be considered optional for cases when the host os has already taken care of permissioning. This commit allows users to disable chown by setting a property on the scheduler-docker-local plugin.
