Add system networking to provider

[internet-diglett]

Overview

Currently Oxide Rack Networking is often managed via direct API calls, which isn't very ergonomic when testing complex configurations. We'd like to extend the Terraform provider to support more of these configurations for both internal and customer use.

Implementation details

We need to support the following features to enable management of rack networking via Terraform:

• System Networking - Address Lots #306
• System Networking - Switch Port Settings #307
• System Networking - Loopback Addresses #308
• System Networking - Static Routing #309
• System Networking - BGP #310
• System Networking - BFD #311

Anything else you would like to add?
