      Mark a recommendation's state as CLAIMED. Can be applied to
      recommendations in
      CLAIMED, SUCCEEDED, FAILED, or ACTIVE state. Users can use this method to
      indicate to the Recommender API that they are starting to apply the
      recommendation themselves. This stops the recommendation content from
      being updated.

     ## EXAMPLES
      To mark a recommendation as CLAIMED:

      $ {command} abcd-1234 --project=project-id --location=global
      --recommender=google.compute.instance.MachineTypeRecommender --etag=abc123
