Added some example playbooks

[Tronde]

IMHO it's useful to have some example playbooks for common use cases that are easy to adapt by copy, paste, and modify.

I like it when roles have an example direktory with some playbooks in it, because it saves time when I don't have to search a long README.md for some examples.

With this PR I would like to contribute some example playbooks for the firewall role. I chose some use cases I encountered in different enviroments.

Thanks for checking the PR. I fixed the name of the task in example/disable-cockpit-and-dhcpv6-client.yml as well as a yamllint error found by the tox check.

Sorry, I missed that second issue with the missing space. I'll do better next time by trying to use the tools at hand in a proper way. As far as I could see I hope to have catched all yamllint issues and tox shoudn't find any others. Thanks for your patience.
