Update conformance tests to handle the update in port redirect semantics

[arkodg]

What would you like to be added:
With an update in the API around port redirect semantics with #1740, the conformance tests pertaining to port redirect do not match this behavior and need to be updated here

Here are the additional cases that need to be addressed

• Port specified in the redirect, and it’s not 80 or 443
• Port specified in the redirect and it is 80 or 443
• No port specified, Listener is 80 or 443
• No port specified, Listener is not 80 or 443

Why this is needed:
To ensure conformance test are evaluating the API correctly
