Improve AS3 to use IP Addressing Discovery

[ripleyhart]

Currently IP addressing must be statically defined for single site use case with AS3 and Webhook (1 to 1 mapping between repo and BIG-IP). CAC specifies IP addresses to be used by the BIG-IP for configuration of components and there is no concept of which environment or site-specific values to enable code/repo reuse.

In regards to DR (where two distinct environments are referencing CAC) IP addressing my NOT overlap, and be unique. Creating a variable or reference mechanism within the repo based on different environments, allows for multiple environments to co-exist while leveraging the same Git repo.

Proposing:
AS3 should be able to pull from a IP Address file (environment dependant) such as GCP or AWS IP Addressing DB's, Git repo or external IPAM DB/dynamic source (future).

If references can be used instead such as {{ vip }} and then based on which BIG-IP the request comes from, populate that address, these would add the correct IP addressing values for different components deployed in different environments.
