Node reporting improvements
    1. Added --pools option to moniitor everything defined in cluster's pool according to choosen option from openvz/qemu/storage.
    So there is no need to update all VM's definitions in pve-monitor.conf everytime when new VM is added. Just ask your cluster administrator to add VMs for monitoring to pool and define it once in your conf

    2. Monitoring options can be used together

    3. Shorten output, for example, to fit text in SMS notification

    4. Line break can be quickly changed from \n to <br> for better representation in nagios logs

    5. Disable Nagios EPN. Usable when script should be called from another perl version. to force enable change to "+epn"
