Custom Field Not Redering in UI in L2VPN Terminations

[kvedder-amplex]

NetBox version

v3.3.1

Python version

3.8

Steps to Reproduce

1. Create a custom field, assign it to the L2VPNTermination Model. I tried "text" and "object".

Expected Behavior

I expected to be able to edit the custom field in the UI.

Observed Behavior

The custom field doesn't appear in the UI. It does appear in the API. I did not see this fixed in 3.3.2, as best I can tell.

I think #5509 may have caught this, and may prevent this in the future?

[DanSheps]

I don't think it will catch it completely.

This is likely because we use a custom form on the termination edit to handle the various different types of terminations.

[kvedder-amplex]

Yeah I am putting in a PR right now. I think netbox/templates/ipam/l2vpntermination_edit.html is missing the code to render the custom fields.
