Preflight CORS Fix

Motivation

The current configuration does not handle CORS preflight requests correctly, leading to potential issues when making cross-origin requests to the API. This can result in failed API calls and a poor user experience.

Summary of Changes

1. Chart Version Update:

   • Updated the chart version from 0.68.0 to 0.69.0 in charts/hub/Chart.yaml to reflect the changes.

2. Ingress Configuration:

   • Added a server snippet to handle CORS preflight (OPTIONS) requests by returning a 200 status code in charts/hub/templates/kerberos-hub/hub-api.yaml.
   • Ensured that this configuration is only applied when kerberoshub.oauth2Proxy is enabled.

Benefits

• Improved Cross-Origin Resource Sharing (CORS) Handling: By correctly handling preflight OPTIONS requests, this change ensures that cross-origin API calls can be made successfully.
• Enhanced User Experience: Users will experience fewer issues with API calls, leading to a smoother and more reliable interaction with the application.

This fix is crucial for enabling seamless cross-origin requests and improving the overall reliability and usability of the API.
