Title: Add link to setup module when ansible vars first referenced.

Add a cross-reference link to the setup module documentation, so users know where to look to find more detail about what ansible variables are available.

(This was a point of confusion for me when first reading the docs, couldn't figure out where the `ansible_*` vars were discussed).
