      Create a Memorystore Memcached instance.
    description: |
      Create a new Memorystore Memcached instance with the given name.

      This command can fail for the following reasons:
        * An instance with the same name already exists.
        * The active account does not have the necessary permissions to create instances.
    examples: |
      To create a Memcached instance named 'my-memcache-instance' in region 'us-central1'
      with 3 nodes, each with 2 CPUs and 2GB of memory, run:

        $ {command} my-memcache-instance --region=us-central1 \
            --node-count=3 --node-cpu=2 --node-memory=2GB
