Override less Ansible settings (#224)

* Do not escalate privileges by default

* Do not disable host key checking by default

* Do not mute deprecation warnings by default

* Provide ansible.cfg only as an example

The new example file does ONLY contain options that are related to this
playbook.

* Remove explicit inventory path from scripts

The inventory file is specified in ansible.cfg, see README.md.

 If multiple hosts are in the master group, the playbook will automatically set up k3s in [HA mode with etcd](https://rancher.com/docs/k3s/latest/en/installation/ha-embedded/).
 
+Finally, copy `ansible.example.cfg` to `ansible.cfg` and adapt the inventory path to match the files that you just created.
+
 This requires at least k3s version `1.19.1` however the version is configurable by using the `k3s_version` variable.
 
 If needed, you can also edit `inventory/my-cluster/group_vars/all.yml` to match your environment.
