Provide a gateway-api sunburst view for primary conformance test targets

[heyste]

Primary conformance test targets;

• cilium
• contour
• istio

APISnoop sunburst view will provide clearly what gateway-api endpoints are hit by the current conformance suite.

[heyste]

Current UX planned for now.

Looking at howto

• wire these changes to the current "release" structure that apisnoop uses
• iterate through the changes locally due to the number of github references

[heyste]

Latest iteration is using resources/coverage/implementations.yaml to connects the UI to the various backend json files.

• Still working through the UX for the gateway api links
• Looking at filtering the current "implementation" from the set of displayed links
• Current site has some performance issues as it's reloading multiple files a number of times. Need to work through the initial loading of the site / how the reactive updating of various components is causing more network requests.

[heyste]

• The above performance issue has been resolved.

[heyste]

• Implementation: Contour (Gateway-API v1.0.0)

[heyste]

• Update gatewaysnoop UX to use a new implementations.yaml format.

• Each implementation is listed in alphabetical order

• Remove "switch version" button if the implementation has only a single "release"

[heyste]

• Istio v1.22.1 using gateway-api v1.1.0
• https://gateway-api.apisnoop.io/1.1019110.0/
