What would you like to be added:
Layotto not only supports dapr api, but also supports all "trusted protocols",e.g. redis protocal and aws s3 protocal ( #510 is working on it)

Specifically, we can divide layotto API into three types:

• Standard API. This is what we already have.
• Trusted Protocal. For example , we add an "aws s3 API".
• Trust Native Protocal. For example, layotto support redis native protocal

I will submit a PR to add support for redis API.

Why is this needed:
That's a long story. To be short, current dapr api can not meet all the needs of applications in the real world while maintaining portability, but protocals like redis protocal and aws s3 protocal can.
For more details, I have a presentation for it .
