Introduce protocol in connection_manager and client_cmdmanager for register and activation users method.
I will use this for daemon activation.
Changed daemon config structure, now the socket configuration are inside the relative method and there is a new key activate.
Activate will be used to indicate if the user is active.
Fixed bug in load_cfg method into client_daemon.
When we load the config form file we lose the order because we use a Dictionary instead of Ordered Dictionary.
Replaced build_default_cfg with save_cfg method.
Now we can manipulate the cfg after the first load to save modification.

Modified load_cfg method to use the new implemantation.
Simplified cfg loading.
Moved initialization of observer and relative operation in new method _initialize_observing.
Implemented the use of activation status.
N.B: this commit is BROKEN. Don't use for execution.
Created _activation_check method into client_daemon.
This will be used to check if the registration and activation is used and when is all gone right activate the daemon observing.
N.B: this commit is BROKEN. Don't use for execution.
Created ALLOWED_OPERATION constant.
This will be used to allow only activation operation from client_commandmanager.
Implement new activation status.
Now client_daemon will be wait until the status of self.cfg['activate'] become True to start the polling and observation.
This will be happen only if a user is activated.
N.B: this commit resolve the last BROKEN commit.
Fixed minor bug.
Now we create local_dir_state only if there is something to write.
