Distributed file system

A work in progress implementation of a Chord based Distributed File System

Completed :

1. Consistent Ring based Hashing
2. [WIP] Implementation of Distributed Hash Table

Implementation details

1. Consistent hashing using the fast xxhash in order to get well distributed but fast hashing
2. Dependency of Protobuf for creating Client-Server API interface
3. Implemented circular finger update instead of Random to get a faster implementation
4. Field-wise Mutex allow two non intersecting R/W operations to happen simultaneously

Based on implementations of consistent hashing by xring, xxhash, chord, rbtree
