Stop running ansible-lint on this repo

It is buggy (throwing exceptions for undefinied variables which are
actualyl defined via set_fact), and we frequently run into problems
using it in this repo.  It was designed to lint roles for Galaxy,
not the way we write ansible.  As of the 5.0.0 release it's
generating >4.5K lines of complaints about files in this repository.
