dhcpv6-pd: pppoe: T2506: restructure CLI

Rename the CLI nodes for prefix delegation from "dhcpv6-options delegate
<interface>" to "dhcpv6-options prefix-delegation interface <interface>".

The change is required to add the possibility to request for specific prefix
sized via the CLI. That option was not possible with the old configuration
tree.
