Change to FQCN with ansible-lint fixer (#553)

* Change to FQCN with ansible-lint fixer

Since ansible-base 2.10 (later ansible-core), FQCN is the new way to go.

Updated .ansible-lint with a production profile and removed fqcn in skip_list.
Updated .yamllint with rules needed.

Ran ansible-lint --fix=all, then manually applied some minor changes.

* Changed octal value in molecule/ipv6/prepare.yml
