In this commit, we modify the way we handle FeeInsufficientErrors to more aggressively route around nodes that repeatedly return the same error to us. This will ensure we skip older nodes on the network which are running a buggier older version of lnd. Eventually most nodes will upgrade to this new version, making this change less needed. We also update the existing test to properly use a multi-hop route to ensure that we route around the offending node.
routing
The routing package implements authentication+validation of channel announcements, pruning of the channel graph, path finding within the network, sending outgoing payments into the network and synchronizing new peers to our channel graph state.
