Release async-nats v0.22.0

Overview

This release introduces a number of changes and two breaking changes:

JetStream publish

Used to return ack:

let ack = jetstream.publish().await.unwrap();

But while adding publish that does not wait for an acknowledgement before returning,
we realized that we can leverage IntoFuture, so the new api is:

// This publishes the message, but do not wait until ack is received.
let future_ack = jetstream.publish().await.unwrap();
// to receive the acknowledge, `await()` the returned value:
let ack = future_ack.await().unwrap();

Event logging

After adding the initial retry on connect option, Event::Reconnect didn't make much sense.
Hence it was renamed to Event::Connected, which describes the current state without implications about the previous one.
For consistency, Event::Disconnect was renamed to Event::Disconnected.
