ConfigurationAccessService: prevent service from being stopped when app loses focus

This makes the ConfigurationAccessService (formerly ConfigurationFtpService) start in foreground
through the use of a persistent notification so that it isn't stopped by the system after the app
loses the focus on the user's screen, which happens when the user switches to an FTP client
application on the same device.
