ENH: Defining allowed port without traffic source returns no feedback

## Describe the Feature

Additional feedback when `allowed_ingress_ports` argument is set, but no source SG or CIDR is set.

## Expected Behavior

Error or Warning output that setting `allowed_ingress_ports` also requires a source.

## Use Case

Any time `allowed_ingress_ports` is set to non-default value.

## Describe Ideal Solution

Check that a source is set.
