Update method parameters and rewrite the method to use SaveDataSharedFileStorage.
SaveDataFileSystemCreator now requires a FileSystemServer at construction time, so DefaultFsServerObjects must be created after FileSystemServer construction but before FileSystemServer initialization.
- Store IServiceObjects in the service manager that return the usable objects instead of storing the objects directly
- Register FS services in the service manager instead of giving them special treatment
- Give each created HorizonClient its own "process ID"
