For variables to use see [Prometheus Configuration](https://github.com/prometheus/snmp_exporter#prometheus-configuration).
Besides setting the filepath for this option, you also need to add
flag `--config.expand-environment-variables` to `extraFlags`.
If the file path is set to this option, the parameter
`--config.expand-environment-variables` is implicitly added to
`ExecStart`.
Note that this file needs to be available on the host on which
this exporter is running.
