Create fstab if not exists

This is mainly to prevent from failing with no such file or directory
during module execution.

* Strip lookup calls out of inventory variables and clean unsafe data
  returned from lookup plugins (CVE-2014-4966)
* Make sure vars don't insert extra parameters into module args and prevent
  duplicate params from superseding previous params (CVE-2014-4967)

Retr0h/align markdown headers

Enable puppet facts

A fairly trivial change since `Role Name` and `Example Playbook`
will likely be modified anyways.  However, since all the other
sections are aligned properly, felt it would be nice to "clean this up".

Before:

    Role Name
    ========

    Example Playbook
    -------------------------

After:

    Role Name
    =========

    Example Playbook
    ----------------

Currently facter facts omit facts that a distributed via Puppet. This
commit adds the `--puppet` option.

In cases where puppet is not installed, the command sends a warning to
STDERR *but* completes successfully. So should not cause any issues.

The benefit is, filtering can be done based on facts set by Puppet.
