docs: Upgrade VSAN objects version. Upgrade a set of objects' version to new one in batch mode. API caller should
  limit the size of the inputs array, and suggested array size is 500 ~ 1000 initially. (The API will give more
  realistic suggestion after more experiments, then will apply hard limits in future)
  
  @param uuids      The array of objects' UUID which will be upgraded.
  @param newVersion The new version will be applied to objects.

  @throws RuntimeFault
