First step to replace protobuf by jsonrpc. Got error with exchanging Param.
Move controller client to root. Add try catch when register function to jsonrpc server.
Create json_client - can redefine rpc function, else use the default rpc call. Add function get_params_media.
Adapt to the missing feature - cannot use kwargs and args in the same time for the manager - remove all kwargs.
Transfert only serializable object from server to client.
Moving in one place when try connection.
Finish migration jsonrpc.
Adding log when receive command in the manager.
Don't close the server when client is closed. Add shutdown jsonrpc when closing server.
