T4997: add dhcp client user hooks
This commit adds a script to run user-defined hook scripts upon renewing a DHCP lease. This can be used to, for example, dynamically define a firewall address-group based on the dynamic IP address of an interface. For an example of its use (as well as the use case I had in mind while coding this), see https://vyos.dev/T2196#142394 Co-authored-by: br <git@ibeep.com>
