Fixes: #442
We're making it absolutely clear which methods do JSON (most of them)
and which do gRPC. We have the ability to do both 'raw' functionality
and optimized paths for JSON+HTTP and gRPC+Protobuf for invoke. We're
not going to add 'raw' or Protobuf support for other building blocks
until there's a specific use case.
For the most part the functionality that's being removed here isn't used
anymore since that was part of the invoke changes.
* Use protobuf packaging for the Any type
This pull request implements two converters which help with the type conversion between arbitrary types and the protobuf `Any` type. The C# protobuf library provides a mechanism to pack or unpack protobuf messages to `Any`. It provides the methods `Any.Pack` and `Any.Unpack` to serialize/deserialize messages based on `Google.Protobuf.IMessage`. For types that are not based on `Google.Protobuf.IMessage`, the existing JSON serialization/deserialization will be used.
I've also cleaned the existing codebase a little bit.
