New Akka.Analyzer Rules

We've added three new Akka.Analyzer rules, AK2003, AK2004, and AK2005. All of them addresses the same Akka anti-pattern where a void async delegate is being passed into the ReceiveActor.Receive<T>() (AK2003), IDslActor.Receive<T>() (AK2004), and ReceivePersistentActor.Command<T>() (AK2005) message handlers.

Here are the documentation for each new rules:

• AK2003 documentation
• AK2004 documentation
• AK2005 documentation
