REQUIRED FLAGS
     --dry-run
        Validate the changes, but do not execute it.

OPTIONAL FLAGS
     --description=DESCRIPTION
        Description for the game server cluster.

     --preview-time=PREVIEW_TIME
        This attribute is only relevant for preview (--dry-run). It is used to
        validate the state for a future time.

     --update-labels=[KEY=VALUE,...]
        List of label KEY=VALUE pairs to update. If a label exists, its value
        is modified. Otherwise, a new label is created.

        Keys must start with a lowercase character and contain only hyphens
        (-), underscores (_), lowercase characters, and numbers. Values must
        contain only hyphens (-), underscores (_), lowercase characters, and
        numbers.

     At most one of these can be specified:

       --clear-labels
          Remove all labels. If --update-labels is also specified then
          --clear-labels is applied first.

          For example, to remove all labels:

              $ gcloud alpha game servers clusters update --clear-labels

          To remove all existing labels and create two new labels, foo and baz:

              $ gcloud alpha game servers clusters update --clear-labels \
                --update-labels foo=bar,baz=qux

       --remove-labels=[KEY,...]
          List of label keys to remove. If a label does not exist it is
          silently ignored. If --update-labels is also specified then
          --update-labels is applied first.
