Removal of `idle_network` in 4.7 broke private COM networks

[bradleyharden]

It looks like the internal event system for the COM system was updated to use the new event system. But in the process, idle_network was removed, which broke users who had set up private COM networks. I don't have strong feelings one way or the other, but you should probably either restore idle_network and friends or deprecate and remove support for private networks.

You're right, that shouldn't have been removed but I guess you were one of the few using private networks. Anyway, can you see if declaring your own idle_network with the value new_basic_event(com_net_event) works?. new_basic_event is available from vunit_lib.event_private_pkg. That's a private package but I want to make sure it solves your problem before re-instantiating idle_network again.
