- Adds a new message handler for HttpClient interop
- Adds an easy way to create HttpClient instances
- A bunch of sample cleanup/polish/simplification
The main thing here is the added ability to interop with HttpClient. We'll be making some future changes to the service invocation APIs in DaprClient to address dapr/dapr#2342 since that issues greatly simplifies the interface we're dealing with.
Fixes: #526
