Gateway doc needs improvements regarding inter Gateway listener conflicts #4161
Description
What would you like to be added:
Clarify on our docs and API docs what should happen when 2 distinct Gateways have a conflict on a listener. Per the discussion on our community meeting: https://youtu.be/AShtmkJXAR8?si=qFA86Z21O7ncoqsL&t=1032
- Two Gateways CAN have the same listeners, even if they conflict, as each gateway should be an independent instance
- Implementations that merge all of their listeners on a single proxy instance SHOULD work internally on the listener isolation
- Implementations that merge all of their listeners on a single proxy but can't isolate the bind/listener MUST add a condition to the Gateway (this is Implementation Specific)
Why this is needed:
Clarify when conflicts may exist
