Edit Interfaces in Almanac with EditEngine

Summary:
Depends on D19323. Ref T13120. Ref T12414.

Move editing to modern stuff and fix some implementation errors from D19323 (mostly copy/paste stuff).

Test Plan:

• Created and edited interfaces.
• Tried to create/edit an interface with a bogus/empty address/port, got errors.
• Tried to create an interface on a bogus device, got an error.
• Tried to create an interface on a device I could not edit, got an error.
