Use hardware address in name generation for DDNS update requests

name: kea-dhcp4 Name Generation for DDNS Update Requests
about: Use hardware address (or something else) instead of ip address

Some initial questions

• Are you sure your feature is not already implemented in the latest Kea version? Yes
• Are you sure what you would like to do is not possible using some other mechanisms? Maybe with hooks?
• Have you discussed your idea on kea-users or kea-dev mailing lists? No

Is your feature request related to a problem? Please describe. The automatic generation of a name for the DDNS update request is: [generated-prefix]-[address-text].[qualifying-suffix]. I need a name because I don't know the IP address, but this auto generated name contains the IP address... I need to manage some equipments that don't request the hostname or don't have it set.

Describe the solution you'd like A solution can be to mangle the hw address instead of the IP address, or the possibility to choose. An example: aa:bb:cc:dd:ee:ff -> aa-bb-cc-dd-ee-ff

Describe alternatives you've considered Write an hook...
