Improved CLI Manager with major improvements

- The manager must be run as root to perform some tasks (write new configuration, restart the daemon, …)
- CentralReport must be already installed on the current host to run the CLI Manager
- The configuration for the internal web server is now written in the configuration file
- The daemon restart when the user exit the CLI Manager to use the new configuration

PS: We must work on the "feature-webservices" branch to finish this PR for the "Online configuration" part.
