• Call with traceIdMustMatch=false (default)
The endpoint either sets the used-defined value or a random string as new traceId for the tag.
  In case of a tag deletion, the endpoint removes the tag from the corresponding object without checking the current traceId of the tag to be deleted.
• Call with traceIdMustMathtraceIdMustMatch=true
  An update or deletion endpoint takes the traceId from the request and compares it to the current traceId of the requested tag. The update or deletion operation will be performed only if the values are matching. Thus, the tag can only be updated or deleted if the previous traceId is known to the caller.
  In case of a tag creation, this condition would never match and should therefore not be used.
