#14446 Initialize loggers before reading cloud config files

Cloud services are configured from RiaApplication::initialize(), which runs before the subclasses append their logger instances. All messages from the cloud config file search were therefore dropped. Add a virtual initializeLoggers() called before the cloud configuration is read, and move creation of the file logger and the std out logger into the overrides. The message panel logger depends on the main windows, and is still created in RiaGuiApplication::initialize().

Do not write fields with IO disabled to the application store, mirroring the check already present when reading. This stops the cloud service configuration from being persisted into the user preferences file.
