  This command deletes a quota override for a consumer. The supported consumers
  are projects, folders, and organizations. The override ID can be found from
  list command output.

  ## EXAMPLES

  To delete a quota override for a project with project number, run:

    $ {command} --service=example.googleapis.com --consumer=projects/12321
      --metric=example.googleapis.com/default_requests
      --unit=1/min/{project}

  To delete a quota override for a project with project ID, run:

    $ {command} --service=example.googleapis.com --consumer=projects/hello
      --metric=example.googleapis.com/default_requests
      --unit=1/min/{project}

  To delete a quota override for an organization, run:

    $ {command} --service=example.googleapis.com --consumer=organizations/555
      --metric=example.googleapis.com/default_requests
      --unit=1/min/{project}

  To force the deletion of a quota override, run:

    $ {command} --service=example.googleapis.com --consumer=projects/12321
      --metric=example.googleapis.com/default_requests
      --unit=1/min/{project} --force
