Configuration of filebeat modules

[DominiqueFuchs]

Hi there,

As I'm using filebeat modules, I'm currently using a custom template for the ansible role. After looking through your repo to see if any configuration options (or jinja template snippets) exist, I noticed they don't and I'm not the first one (fixes #26 - and after creating the PR I also discovered #46 and #48).

This PR does

1. Add a template snippets for the module configuration (the default one that ships with filebeat installation)
2. Makes the snippet dependant on three new variables for the role configuration
3. Adds the aforementioned variables, again with filebeats default values
4. Makes note of the options within README.md

I did a (admittedly really quick) search if false would be a better default because of version differences, but AFAICT these corresponding functionality and path values existed like forever so I went with true, which resembles the state after a manual filebeat installation anyway.

Greetings 👋🏻
