In our quest to move calls to the ControlTower into the main payment
lifecycle loop, we move the edge case of a too long route out of
createNewPaymentAttempt.
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.
