Request: Support Setups with ALB/ELBs in front of the Service Box

[Aghassi]

Currently, due to other services not being in AWS, our team uses dnsmasq to route traffic to specific domains. dnsmasq is installed on the service box, but the service box can't be in different subnets (for obvious reasons). So, we front the service box with two ELBs. One that goes public and the other which is internal. The internal one handles a VPN connection to legacy services not in AWS. dnsmasq is then able to route traffic to these instances via the VPN. Currently, the provided script does not take this into account in anyway, and thus is a manual process. Though I have taken some cracks at it, it gets cumbersome because of things like HTTPS certs. If you set any HTTPS ports on the ELB, you need to provide a cert. Since CircleCI doesn't use certs that Amazon provides (you need to generate them then add them), this is a little more difficult to script (doable, but not impossible).

Ultimately, I'd like to see more complex use cases supported by this script if possible.
