DO "reachable" via a different IP address

[fchmainy]

Is your feature request related to a problem? Please describe.

When composing a DO declaration specifying BIG-IQ licensing parameters for a "reachable" set up, DO automatically takes the BIG-IP management (private) IP as the target for licensing.

In my case, BIG-IPs are deployed in public clouds and their mgmt interface are attached to a private IP mapped to a public IP. So in this case, licensing fails.

Describe the solution you'd like

I would like to have, somewhere in the declaration, an extra IP address attribute for the public IP address mapped to the mgmt NIC so BIG-IQ can reach the BIG-IP.
