I'm creating a puppet module which get's its settings from the user in a yaml format (I use the loadyaml function for that). Where should I put this file in the puppet module? both "files", "templates" directories don't seem to fit.. I prefer (if possible) not to set an absolute path for that file, since I don't want it to depend on the user..

This is what Hiera is for. Just make sure your module class is parameterized, then the user can either pass in those parameters manually, or they can define them in their own Hiera data and you don't need to worry about the YAML file location (or even whether it's YAML).

For example, in the puppetlabs-tomcat module the tomcat class has a $catalina_home parameter. I can define that in a tomcat::catalina_home key in my Hiera data. The naming is automatic; you don't need to do anything special.

on which directory inside the puppet module would you put that yaml file?

It goes wherever the user wants to put it. The default is /var/lib/hiera. If you want to store default parameters for your module that the user can override, at the moment you'll need to create a `::params` class or similar. Puppet 4 improves support for module-provided data.
