[FR] Option to create ALB Target group on a NLB

[raffidahmad]

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

A service running on ECS requires a static IP address. However, the existing Application Load Balancer (ALB) does not provide a static IP, which complicates the setup.
One solution is to

• NLB listener port X -> ALB Target group on port X
• ALB listener port X -> Target group port X -> ECS

Describe the solution you'd like
compose-x should support the option to add ALB target group while configuring a load balance and also lookup for elastic IP addresses.
I suppose the default behavior where the EIP is assigned by AWS could also be changed?
