0.8.3

• Extendable system health check - add the ability to register custom actor implementations to be part of the health check:

If any of the system actors take longer than 1 second to respond to a GetStatus, the health check will report the health status as Degraded.
If an error is returned from any of the actors, the health check will report it as Unhealthy.
Health check also provides useful information such as currently active cluster peers and version information.

• Shards will now start entities asynchronously and are no longer blocked by individual entity recoveries, messages will be buffered until the shard receives confirmation that the actor has started successfully.

• HTTP API Swagger + openapi powered by utoipa crate.
