IP space discovery and reconciliation

Brownfield discovery and migration from "unknown" network into a source of truth as netbox is challenging.

building the knowledge of your inventory, with knowledge about all the vendor/model and all its IPs assigned to the device is often manual and very timeconsuming.
create a plugin that scans the requested subnets, using ping, snmp, ++ to analyse the devices on the subnet.
the "box_scan" should build a staging_model of all the discovered vendor|model|linecards|++ and all its IPs assigned to the device, and then be able to "approve" the device to mastered by NBX. when the user "approve" the device it will be moved from the staging_model and into the netbox model.
