InstanceIpToNodePrimaryIpQuery: use a query dict

In 95b487bb we changed InstanceIpToNodePrimaryIpQuery to be able to query
multiple instances at once. We also need to be able to query ips
belonging to a specific nic link, so what we do is:

1) Move the "query" argument to a dict, containing different fields
2) Explicit the "query for a single ip" or "query for a list" options.
