Depends on D4861
Adding initializing function in rust to be called from the c++.
The goal here is to:
- **spawn a thread in rust that will listen on a thread-safe queue** (`initialize`)
- schedule some data on this queue (`process`)
- gracefully exit the thread and release all resources (`terminate`)
Later on, in the spawned thread, we will connect to the blob service through the gRPC, but first things first.
