docs: // HasDiskCreationOperations is an exported function that checks a list of
  // device changes to see if there are any disk creation operations. This should
  // be used to check if ReconfigureVM should be done through the Storage DRS
  // API, as a Reconfig operation done through SDRS without new disk operations
  // will fail.
