With start of multi-vif support we've merged a new format of Pods
annotations i.e. dictionary with interface names as keys and VIF o.vo's
as values. This is inflexible, as we don't get versioning of the
dictionary.
This commit switches that dictionary to oslo.versionedobject of
following structure:
PodState
- default_vif: VIFBase
- additional_vifs: {
'<ifname>': VIFBase,
...
'<ifname>': VIFBase,
}
This should help us if we ever decide to change this format.
