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

* docs: update browser example pubsub
* docs: fix pubsub example config
* fix: make pubsub default to enabled
This allows for only adding the module to have it enabled. Previously you would have to supply and enable the module which is unncessary for users

https://github.com/multiformats/js-multiaddr/pull/76 changed the
default protocol from ipfs to p2p.
js-multiaddr is a transitive dependency of peer-info, so in order
to get this change, we had to bump the version of peer-info.
* fix: revert ipfs -> p2p change for some tests
As per PR feedback. Needed for backwards-compatibility.
