fix: restore ability to dump all configuration

When running `kayobe configuration dump` would fail with

```
...FAILED! => \n    msg: to_nice_yaml - 'hostvars'. 'hostvars'
```

This is due to the existence of variables that use `net_ip` filter.
Therefore, this can be avoided by using `lookup` filter.

Some of these changes are done within config and would be picked
automatically. However some changes are done within the documentation
and would require a user to update their configuration to benefit from
the changes suggested.

Note: This only works with you use `--limit` as the firewall
configuration is within `all` group and gets evaluated by hosts that
do not have network_interfaces such as switches. Due to the command
producing a lot of output running the command without a `limit` it not
advisable.
