WifiServiceImpl: add empty calls for LOHS

Add new calls to start/stopLocalOnlyHotspot and start/stop observing
hotspot updates.  The calls will be exposed in a later CL.  The calls
throw the UnsupportedOperationException until the implementation is
complete.

Also added tests to verify the exceptions are thrown.
