v0.11.0: Brand new "Sorock"

Previously called "lol" or "lolraft" now reborn as "Sorock". Sorock is a multi-raft implementation in Rust.

The project started as a single raft library called lol, which was a abbreviation of "Lane on Log". Last year, I started to redesign the entire codebase into supporting multi-raft, which I believe "Must" in implementing serious distributed system.

Since then, it took more than a year as a side work project. And now I am enough confident to release a new version, which will lead to v1.

To reach v1, I think it is very important to design the internal more convincing: Making use of the Rust's static type system to gain more guarantees is a good software's trait.

I will continue polishing this software to make the best Raft library in the world.
