This commit makes sure that REST API version 1 is used when the user has selected to use IoTDB 0.13 or 1.0 Fixes: https://emqx.atlassian.net/browse/EMQX-9920
The previous name for the version option was v1.0.x which is clearly wrong since this option was tested against IoTDB version v1.1.0. This commit fixes this by renaming the option to v1.x. Fixes: https://emqx.atlassian.net/browse/EMQX-9926
