Example Playbook
----------------
1) Just install rsyslog with default configuration (it will be placed in /etc/rsyslog.d/)
```yaml
- hosts: all
  remote_user: root
  sudo: no
  - roles: 
    - { role: rsyslog }
```
2) Install rsyslog, without default configuration and setup two different custom stanzas
```yaml
- hosts: all
  remote_user: root
  vars:
    rsyslog_default_config: False
  roles:
  - role: rsyslog
    items:
    - name: "20-iptables"
      lines: 
        - ':msg, contains, "iptables" /var/log/iptables.log'
        - '& ~'
    - name: "30-dovecot"
      lines: 
        - 'if $programname == "dovecot" and $syslogseverity <= "6" then ~'
        - '& ~'
```
3) Install rsyslog, specify a custom configuration template
```yaml
- hosts: all
  remote_user: root
  vars:
    rsyslog_default_config: False
    rsyslog_custom_config: /home/servers/foo.bar/templates/rsyslog_custom.j2
  roles:
  - role: rsyslog
```

4) Install rsyslog using official repository packages, use major release 7
```
- hosts: all
  remote_user: root
  roles:
    - { role: rsyslog, "rsyslog_use_repo": True, "rsyslog_repo_releasever": 7 }
```

5) Enable a simple rsyslog UDP server (receiver) for remote logging
```yaml
- hosts: all
  vars:
  roles:
  - role: rsyslog
    rsyslog_server_udp_port: 514
    rsyslog_server_udp_address: 192.168.200.201
```
