Description
Improved initial connection times from a dht perspective for nodes at startup when all previous connections to peers failed, as well as when a node lost all connectivity. With this PR a node will attempt to connect to peers with previously failed attempts under such circumstances, improving general connectivity. Nodes will refresh their dht neighbour list without discriminating against those peers so that all nodes can be tried again.
Motivation and Context
When a node starts up or loses all connectivity and all known peers have had a failed connection, the node will wait for a 24-hour cooldown period before the same nodes are contacted again.
