Add support for dual-stack external addressing

- Adds enum for tracking the external IP addresses for an instance or
  service, which includes the three fields that were previously
  separate: SNAT, ephemeral, and list of floating addresses.
- Makes the previous source NAT config type IP address specific, with a
  "generic" variant for services. This is a bit lazy, but we can lift
  the IP version out of the contained IP address and into the source NAT
  type itself in the future if we need to.
- Add new version of the sled-agent API with these new types, plus
  conversions with the previous version
- Completely handle dual-stack OPTE ports, closes #9247
- Closes #9318
