When the client has a connection to one of the hypervisor specific daemons (eg virtqemud), the app may still expect to use the secondary driver APIs (storage, network, etc). None of these will be registered in the hypervisor daemon, so we must explicitly open a connection to each of the daemons for the secondary drivers we need. We don't want to open these secondary driver connections at the same time as the primary connection is opened though. That would mean that establishing a connection to virtqemud would immediately trigger activation of virtnetworkd, virnwfilterd, etc despite that that these drivers may never be used by the app. Thus we only open the secondary driver connections at time of first use by an API call.
