"Secure" or "SameSite" attributes cookies for the HAProxy router in OpenShift

Issue

• The HAproxy version shipped in OpenShift Container Platform to expose Routeobjects does not support adding attributes like "Secure" or "SameSite" to the issued routing cookies (used to re-target pods).
• Modern web browsers (e.g.: Google Chrome) are changing the default behavior for how cookies will be sent in first and third party contexts. As a result, the sticky sessions configured in HAproxy will no longer work.
• Any cookies used by a site will be considered as third-party cookies when the site is displayed within the frame.
• For cookies needed in a third-party context, it will be required to ensure they are marked as SameSite=None; Secure.
