Before this commit the commands that listed tunnels and tunnel routes would be limited to 1000 results by the server.
Now, the commands will call the endpoints until the result set is exhausted. This can take a long time if there are
thousands of pages available, since each request is executed synchronously.
From a user's perspective, nothing changes.
This commits makes sure that cloudflared starts using the new API
endpoints for managing routes.
Additionally, the delete route operation still allows deleting by CIDR
and VNet but it is being marked as deprecated in favor of specifying the
route ID.
The goal of this change is to make it simpler for the user to delete
routes without specifying Vnet.
