Valentin Shergin fd3b8f2000 Fabric: Introducing Better: For faster, clear and ideomatic codebase
Summary:
`Better` is a trivial collection of basic tools borrowed from other low-level general purpose libraries (like Folly, Abseil or Boost). The main goals of Better:
 - Make the codebase more portable;
 - Make the dependency list explicit (by decoupling it as a dependency list of Better);
 - Make relying on modern C++ patterns and tools in code simple and easy.
 - Make executing experiments with different dependencies easier.

 As a first example usage, this diff replaces std::unordered_map with an efficient one from folly on the one of the hottest paths.
