Move/remove include_vars in tasks/main.yml?

[rbjorklin]

I was just hit by some surprising behavior due to the Ansible variable precedence rules where the include_vars block in tasks/main.yml overrode my configuration that I had set in "14. play vars_files". Since include_vars is at position 18 in that list there are very few options for overriding the configuration in vars/RedHat.yml. Could the role be reworked to respect configuration set in at least step 12 and onwards?

For reference a similar issue has been brought up in the past #49.
