Sets the maximum age of the {@link Watch}. If the {@link Watch} is older than this value,
it is closed and a new one is created. If unspecified, {@value DEFAULT_MAX_WATCH_AGE_MILLIS} ms will be
used. {@code 0} disables this feature.

<p>This option would be useful when the long-lived {@link Watch} becomes stale due to a network issue or
a bug in the Kubernetes Server.
