The previous implementation relied on the order of traversal of a hashtable, which isn't exactly reliable. It wasn't problematic because the semantics of the port pair are symetrical, but since we're planing on using the YAML netplan generator backend as a passthrough for `netplan set`, we want to preserve the user's input as pristinely as possible. The new implementation uses the ordered list of netdefs to determine the order in which netdefs are processed, which is both deterministic and sensible, since it respects the order in which the user fed us the info (modulo the grouping by devtype).
Later in the patchset we expose this data to Python, and are using the names rather than the integers to represent the netdef types. As a result, we need a proper name for this type to distinguish it from the default value.
Contrary to all other def types, this one is "virtual", as it doesn't have a YAML key matching it. Prefixing it with an underscore should make it obvious that *something* is different there. Co-authored-by: Lukas Märdan <slyon@ubuntu.com> Co-authored-by: Lukas Märdian <slyon@ubuntu.com>

Description
A couple of patches related to OpenVSwitch handling. The consistency patch is needed to be able to ensure idempotency of the user input (within reason). The type name definition will be needed when we'll rewrite
sriov.pyas we'll need to identify those definitions.Checklist
