Is it possible to use custom fields within module config file? What is the appropriate hierarchy?

For example in apache2 module

```
- module: apache2
  access:
    enabled: true
    var.paths: ["/var/log/apache2/access.log", "/var/log/apache2/other_vhosts_access.log"]
    fields:
      token: <my-token-here>
      type: apache_access

```

I don't have any issues using "fields" dictionary within inputs but I'm not seeing the custom fields added when using "fields" inside modules.d/apache2.yml

Hey @mattz  
Please take a look at [configuring templates (link)](https://www.elastic.co/guide/en/beats/filebeat/current/configuration-template.html) and make sure you have **`append_fields`** configured.

if this does not help you can try to run  
`./filebeat setup --template`  
on top of that
