emissary: HTTP and HTTPS listeners don't work together

Describe the bug I can’t use HTTP and HTTPS listeners together without “redirect_cleartext_from”.

To Reproduce Add the below annotation in the ambassador service:

apiVersion: ambassador/v0
kind: Module
name: tls
config:
  server:
    enabled: True

Expected behavior I want to create HTTP only services and HTTPS only services, but I can’t. When I enable the TLS module, the HTTP port in the pods is closed. So, to have both listeners opened, I need to use the “redirect_cleartext_from”, so all HTTP request are redirect to HTTPS.
