Using local-hostname instead of hostname in user-data fixed the issue
According cloud-init doc, https://cloudinit.readthedocs.io/en/latest/topics/datasources/nocloud.html for NoCloud data source, the permitted key is h or local-hostname. so using local-hostname instead of hostname in user-data fixed the issue. Close this bug as NOTABUG.
