fix: remove peer routing search-for-self

The peer routing module starts a recurring process that searches for
peers close to our peer id.

This makes the DHT module query the network for peers.  Thing is the
DHT module is already doing this because periodically searching for
peers close to us is in the DHT spec so this ends up making redundant
queries.

This PR removes the recurring task configured by the peer routing module.

+Libp2p uses a datastore implementation for Peerstore persistence and for the DHT state. While libp2p defaults to a datastore implementation, it can receive any implementation of a datastore compliant with the [interface-datastore](https://github.com/ipfs/js-ipfs-interfaces/tree/master/packages/interface-datastore) via its configuration.
+
+In this release, we updated to `interface-datastore@6.0.0`. As a result, libp2p users relying on a configured datastore should update it to a compliant implementation for updating libp2p.
