Main REST API of Gargantext (both Server and Client sides)

TODO App type, the main monad in which the bot code is written with.
Provide config, state, logs and IO
 type App m a =  ( MonadState AppState m
                 , MonadReader Conf m
                 , MonadLog (WithSeverity Doc) m
                 , MonadIO m) => m a
Thanks @yannEsposito for this.
