Add support for Infiniband GUIDs

v3.5.9 (but we plan to upgrade soon)

I'm a NetBox Labs customer

Proposed functionality

I would like to be able to configure an Infiniband System GUID on Devices, as well as a Node GUID and Port GUID for each Infiniband Interface (ex: the Nvidia Bluefield card).

In practice the 3 GUID types may all be the same on a device with a single Infiniband interface, but we want to support the other cases as well, such as:

• An independent switch has one System+Node GUID but many interfaces, and each interface has a different Port GUID
• An HCA may have one System+Node GUID, but multiple interfaces, and each interface will have a Port GUID
• A server may have multiple HCAs (interface cards), each with their own Node GUID, but they all share a single System GUID
• A modular Infiniband switch will have a Node GUID for each module, but they share a single System GUID. Each module will have multiple interfaces with their own Port GUIDs.

Use case

This would allow recording physical port and device addresses, which will enable mapping logical links to physical locations.

Database changes

From database point of view, varchar 59 seems fine.
