IPAM Webhook System Support

[dronenb]

Title

IPAM webhook support

Description

Allow hitting a remote endpoint for IP + hostname allocation/release. This would allow for interaction/interoperability with systems that may be internal only (IE, non public facing API's).

Actual Problem

Presently, the only providers supported for IPAM are the FIC and Infoblox.

Solution Proposed

Allow support for arbitrary webhook for IP allocation/release, similar to Cert-Manager and ExternalDNS do:

https://cert-manager.io/docs/configuration/acme/dns01/webhook/
https://github.com/kubernetes-sigs/external-dns?tab=readme-ov-file#new-providers

Alternatives

A pluggable method for introducing new providers.

Additional context

May help w/ the following other issues:

• BloxOne API key support #127
• Add Netbox IPAM provider support #39
• Add BlueCat Networks IPAM Support #11
