[Research] Look into Tokio async and futures

[NullSense]

Perhaps using Tokio would be a good move for this project. However some research needs to be done whether it would be beneficial and if so, how and to look into implementation details.

Perhaps Tokio should not be added, as it is another dependency and the project is meant to be a minimal http server.

Hi, I'm interested in contributing to this, but question though, how much of Tokio do you want to use? Do you want to use in some specific part? Or, do you want an async version of Linda?

@lunchboxav I am not quite sure, this is why I put [Research] into the name of the issue, the project would need to weigh the benefits and drawbacks. One important thing to weigh is how lightweight and dependency-free the project should be. Any opinions or constructive feedback is welcome regarding anything to do with async, parallelisation and runtimes like Tokio.
