* In the event that a bug cannot be automatically backported, the istio-testing bot creates an issue for a failed
    attempt and assigns it to the developer. This issue **is not** sufficient for requesting approval.

    * Large fixes, where the LOC>100 not withstanding unit tests changes, require subject-matter expert approval.

The new Ingress chart uses a 'values.yaml' (see user-example-ingress), which auto-generates Service ports,
Gateways and basic VirtualService. It is still possible to only configure the ports in Service, and do manual
config for the rest.

All internal services ( telemetry, pilot debug ports, mesh expansion ) can now be configured via the new mechanism.
