Bug: Cannot set App Ports to an empty list in ECS Proxy Configuration

[benmurden]

Summary
When trying to define an ECS service that does not expose ports, but should be in the mesh, an error (App ports not found) is returned when creating a proxy configuration that has either an empty AppPorts list, or omits the AppPorts property.

Steps to Reproduce

• Create an ECS service that exposes no ports and has an Envoy sidecar.
• Set the AppPorts to an empty string or omit it.
• Error "App ports not found".

Are you currently working around this issue?
Expose a dummy port on the service.

Additional context
This comment seems to suggest this should be possible.
