And using embed timeline server by default. so here
`RemoteHoodieTableFileSystemView` would send `LATEST_PARTITION_SLICE_URL`
request to the driver. After the handler thread in thread pool of timeline
service in driver received this request, it would call the `sliceHandler` to
`getLatestFileSlice`. And it would create partition path dir if it not exists

I add some logs in the main thread and the new thread of the timeline service.
And found that the user group information in the main thread of driver is
right, but that of new thread is wrong.
