feat(daemon, cli): global DaemonConfig and an ability to get/save it using cli (#174)

* use one global Arc<DaemonConfig>

* implement commands

* replace Arc<DaemonConfig> with Arc<Mutex<DaemonConfig>> and fix pwsp-gui

* add pwsp-cli support

* replace serde_json::to_string_pretty with to_string

* refactor

* implement UpdateDaemonConfigCommand and use it in pwsp-gui so it now uses real in-memory config, not the saved one

* implement utils::gui get_daemon_config and update_daemon_config to simplify code
