Add snmp-exporter to NABOX 4.0.x

[YehudaLevi1999]

Good Morning,

I would like to add snmp-exporter to the NABOX, in order to be able to monitor the mcc-ip backend switches (cisco 9336), so we will be able to visual the bandwidth of the ISL ports , so we will know when we need to add more ports or replace those 40Gb ports to 100Gb.

Thanks in advanced.

Y.
