New testing and cleanup to match

I changed the aio-apache back to default to fix the RACK004 foodcritic
rule, added tests suites for a wrapper cookbook, and for a runlist usage
of the cookbook, and added small changes to the Rakefile to allow
failure in CI environments.
Disable ipv6 for local testing
disable_ipv6 would have applied to remote as well.
