Zync route update removes annotations

When editing an existing route and providing it a new URL, only a portion of this route should be changed instead of the current behavior where it is completely deleted and re-created, destroying annotations and other metadata.

From the client:

a little thing - with the new 2.7 - 3scale version. Everytime I change the configuration of an API in 3scale the zync creates a new route without our annotations - cookie workaround:

~~~

apiVersion: route.openshift.io/v1

kind: Route

metadata:

annotations:

haproxy.router.openshift.io/disable_cookies: "true"

~~~

So every time I have to add this manually. Maybe is there a change to make that workaround a layer higher. So zync make routes with haproxy.router.openshift.io/disable_cookies: "true" ?
