Rust Async Runtime

Priority	MUST
Type of change request	FEATURE
Epic link
Status	DONE
Target release	0.1.0

Vision: Asynchronous programming in highly I\O application like `Iroha` should give better utilization of hardware resources. Async runtimes can give better performance and some OOB functionality for futures handling.

Functional details: Rust provides an ability (via `futures` crate) to abstract over futures executing runtime.

Environmental objectives: None

Reading of Tokio vs Async-Std articles

Important aspects that were identified:

async-std has a safer layer of abstraction
a lot of old libraries heavily depends on tokio

overhead (lower is better)
OOB functionality (contains what we need)
promising future (what runtime can become standard choice in a year)
