chore: release version v0.35.5

Implements the idea from #1060 - allows us to get some insight into what's happening in a libp2p node out side of just bandwidth stats.

Configures a few default metrics if metrics are enabled - current connections, the state of the dial queue, etc.

Also makes the `Metrics` class not depend on the `ConnectionManager` class, otherwise we can't collect simple metrics from the connection manager class due to the circular dependency.

+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.
