    Use and instead of ampersand in description of firewalld service
    
    The ampersand symbol (&) caused issues with firewalld:
    
    ```
    ERROR: Failed to load service file
    '/etc/firewalld/services/monitoring.xml': INVALID_SERVICE: not a valid
    service file: not well-formed (invalid token): line 9, column 74
    ```
    
    For the sake of simplicity I've replaced this symbol with "and".
