Adding Ansible-lint, Ansible-review tests to travis

Ansible-review only .yml files in root and  roles, vars, tests folders

Updated comments

Corrected ansible-lint parameters

Removed a tab character that causes problems with ansible-lint 

See https://github.com/willthames/ansible-lint/issues/166
Fixing Travis Ansible Syntax tests roles path

The ansible roles path had problems due: 
1. Absense of top level global role 'iiab' 
2. Hardcoded paths '/etc/iiab' in ansible.cfg 

Fixing them in a hacky way. :(
