Clarify the notion of the primary interface for an instance #960

There's a related point here, which may deserve its own issue. The current API for creating NICs in Nexus allows clients to specify one of three kinds of data when creating an instance. That's defined here, where the variants have the following interpretations:
I originally made it this way when I thought we'd also support attaching an existing NIC, which is no longer the case. And the issue is that the last variant actually subsumes the others. For example, if you want no NICs, use a list of size zero. We can use default values on the fields of the |

Yeah, I think these are better treated as two separate issues, since the first seems unambiguous — using "default" to mean "primary" internally is basically wrong and needs to be fixed. The instance create API question is separate and a bit more open-ended. #1003 |

We're currently using the term "default" in Nexus to refer to what's called the primary interface in RFD 21. This issue tracks cleaning up at least the language around the primary interface, and possibly including a boolean or some other information in the
network_interfacetable to indicate whether an interface is the primary for its instance.The value of that is it makes it clear which IP addresses to publish in DNS, which one to use when doing NAT for an instance to reach the broader network, and probably other things. One drawback is the need to treat it specially, such as disallowing deletion, at least not without propagating the "primary" status to another interface.
