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 .
```
Because of how plugin commands are implemented, their output can be incredibly verbose. Rather than executing even the `set -eo pipefail` parts of a plugin, we immediately check if the command is implemented by a plugin. If it is not, then we continue on as normal.
One side-effect of this change is that plugin commands need to be duplicated again:
- once in the command array
- once for the actual body of the command
- once in the help output
This is also quite hackish, and probably not the best way to decrease trace output. Note that we drop approximately 2k lines worth of logs with this change.
