etag property
etag is used for optimistic concurrency control as a way to help prevent
simultaneous updates of an alert from overwriting each other.
It is strongly suggested that systems make use of the etag in the
read-modify-write cycle to perform alert updates in order to avoid race
conditions: An etag is returned in the response which contains alerts,
and systems are expected to put that etag in the request to update alert
to ensure that their change will be applied to the same version of the
alert. If no etag is provided in the call to update alert, then the
existing alert is overwritten blindly.
Optional.
