The Logger previously took a *netmap.NetworkMap at Startup and on every ReconfigNetworkMap call, denormalizing it into per-IP and self lookup maps. That denormalization is O(n) over all peers and ran on every netmap update, contributing to the broader quadratic behavior we want to eliminate when a single peer is added or removed. Instead, this makes netlog ask LocalBackend (well, nodeBackend) for the info it needs, letting us remove the netmap.NetworkMap type entirely from the netlog package. This is a dependency to removing the netmap.NetworkMap type from upstream callers, like wgengine.Engine in general.
