Set log_path in system config

[jocobwknight]

Is your feature request related to a problem? Please describe.

I'm setting up AWX to install FluentD on VMs (not in Containers). Ansible's "ansible.builtin.service" doesn't have command line arguments like "-o" because it's using systemctl. So the logs can only be defaulted to /var/log.

Describe the solution you'd like

I'd simply like "log_path" to be an attribute I can set in the section of FluentD's config file. It's an attribute that can be set with command line arguments, but not in the config file.

Describe alternatives you've considered

I could modify the service file to include the "-o" command line argument, or have Ansible modify the code directly like in the system_config.rb file and so on so that attribute becomes available. In either case though it would just be a hacky temporary solution.

Additional context

My /var/log directory is mounted to a low capacity drive because we expected to be able to store all fluent related data in our /opt directory. For now I can set the log rotation very tightly to keep it from filling up, but I think the log path being configurable in the global settings file is a deserving feature that I'm surprised doesn't exist already.
