Robert Klotzner 795a526e6d Do peer connect later (as it happens in reality). (#2971)
Otherwise peer connect events occassionally happen before
`StatementFetchingReceiver` message.
2021-05-03 21:50:32 +02:00
Robert Klotzner dacde443f7 Infrastructure improvements (#2897)
* Factor out runtime module into utils.

* Add maybe_authority information to `PeerConnected` event.

We already gather this information in authority discovery, so we might
as well share it with others.

This opens up an easy path to trigger validators differently from normal
nodes, e.g. for prioritization. This change has become more important
now, that we just connect to all validators and therefore just have a
long peer list without any information about those nodes.

* Test fix.
