Gateway API: Listener Route binding selector kind must match Routes compatible with Listener protocol

[sunjayBhatia]

The kind field of the route binding selector has the following description:

Kind is the kind of the route resource to select.

Kind MUST correspond to kinds of routes that are compatible with the application protocol specified in the Listener’s Protocol field.

If an implementation does not support or recognize this resource type, it SHOULD set the “ResolvedRefs” condition to false for this listener with the “InvalidRoutesRef” reason.

The protocol field is defined as:

Protocol specifies the network protocol this listener expects to receive. The GatewayClass MUST apply the Hostname match appropriately for each protocol:

- For the “TLS” protocol, the Hostname match MUST be applied to the SNI server name offered by the client.
- For the “HTTP” protocol, the Hostname match MUST be applied to the host portion of the effective request URI or the :authority pseudo-header
- For the “HTTPS” protocol, the Hostname match MUST be applied at both the TLS and HTTP protocol layers.

• Process Kind
• Set status on Gateway

The remaining bit here is to set status on Gateway.
