Log output for ps:retire was previously a bit too verbose because we weren't handling the following edge-cases.
- if a container doesn't exist, remove it from the dead container list
- ensure a restarting container is properly killed
- only attempt to stop/kill if the state is not dead or exited
- do not attempt to do anything if the container doesn't exist
- correct check on running state
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 .
```
These will be killed on a cron schedule, allowing us to ensure old containers don't run once memory pressure clears up - even across restarts.
Closes#3225
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.
