			Supporting "--no-property" option will apply user a convenient way to clean all properties of volume snapshot in a short command, and this kind of behavior is the recommended way to devref. The patch adds "--no-property" option in "volume snapshot set" command, and update related test cases and devref document. Change-Id: I5f10cc2b5814553699920c4343995b2e11416e4e Implements: blueprint allow-overwrite-set-options
