Translate non-mapped NetBox fields to Nautobot custom fields

[chadell]

Environment

• Nautobot version: latest
• nautobot-netbox-importer version: latest

Proposed Functionality

Define opinionated translations for some fields that do not exist in Nautobot but the data could be interesting to retain as a custom fields

Use Case

For equivalent data models, some fields from NetBox may not map directly to fields in Nautobot. When this conversion looks desirable, new custom fields may be created and the data imported.
