When the node is shutting down, new connections can still be received.
If this happens we can end up writing into the datastore when it's
been closed which throws an error.
Instead, if we're not running, have the connection manager close new
incoming connections.
We have a peerstore that keeps all data for all observed peers in memory with no eviction.
This is fine when you don't discover many peers but when using the DHT you encounter a significant number of peers so our peer storage grows and grows over time.
We have a persistent peer store, but it just periodically writes peers into the datastore to be read at startup, still keeping them in memory.
It also means a restart doesn't give you any temporary reprieve from the memory leak as the previously observed peer data is read into memory at startup.
This change refactors the peerstore to use a datastore by default, reading and writing peer info as it arrives. It can be configured with a MemoryDatastore if desired.
It was necessary to change the peerstore and *book interfaces to be asynchronous since the datastore api is asynchronous.
BREAKING CHANGE: `libp2p.handle`, `libp2p.registrar.register` and the peerstore methods have become async
BREAKING CHANGES:
top level types were updated, multiaddr@9.0.0 is used, dialer and keychain internal property names changed and connectionManager minPeers is not supported anymore
BREAKING CHANGE: all API methods with peer-info parameters or return values were changed. You can check the API.md document, in order to check the new values to use
