Agent must use async-await interface

[Mec-iS]

The client should implement Python async-await protocol in all of its functions

@Mec-iS please elaborate

[Mec-iS]

Agent should implement wherever possible Python generators and asynchronous co-routines both for calling the servers ([asyncio](asyncio is a library to write concurrent code using the async/await syntax.)) and updating the graph in Redis (possibility of using Streams).

Heracles.ts implements asynchronous behaviour in Typescript (example).
