      Apply software update to nodes in a Memorystore Memcached instance.
    description: |
      Apply a software update to nodes in a Memcached instance to the latest available software
      version.

      To check if a Memcache instance and its nodes have a new software update available, run:

        $ gcloud beta memcache instances describe my-memcache-instance --format="table(updateAvailable.yesno(),memcacheNodes:format='table(nodeId,updateAvailable.yesno())')" --region=us-central1

      Applying a software update to a node causes a full cache flush on that node.
    examples: |
      To apply software update to nodes 'node-1' and 'node-2' of a Memcached
      instance named 'my-memcache-instance' in region 'us-central1', run:

        $ {command} my-memcache-instance --node-ids=node-1,node-2 --region=us-central1

      To apply software update to all nodes of a Memcached instance named 'my-memcache-instance'
      in region 'us-central1', run:

        $ {command} my-memcache-instance --apply-all --region=us-central1
