option to not move private IPs in AWS

[chen23]

Description

Customer observed an issue where they had deployed the across-az CFT template and deployed secondary IPs to the ENIs. When the BIG-IP system was rebooted they observe that the secondary IPs are removed by CFE.

To avoid this issue the customer had to manually disable CFE. Ideally there should be an option for CFE to not disassociate private IPs. This is somewhat similar to #64

In this instance the customer did not need CFE for their requirements (they were using DNS to point to the private IPs in each AZ), but ideally this could be a configurable option to disable removing private IPs unless a customer is working with a same-az deployment.

Closing.

The CFE explicit config solves this issue. Documentation on how to use the explicit config can be found here.
