Title: Expose http header based metadata via api

- Expose `X-Etcd-Index` , `X-Raft-Index` , 'X-Raft-Term' via api
- Write specs against the main Etcd README examples. (I would be good to have `etcd-ruby` having ditto usage example as the main `etcd`)
- Some code changes on main client class to address `prevIndex`, `prevValue` and `prevExist` based test and set operation.
- Make `Etcd::Node` comparable (need a larger debate on the logic for comparison)
