External Jaeger broken for 1.x control planes

External jaeger configuration no longer works for 1.1 control planes.  Previously, users would set global.tracer.zipkin.address=jaeger-collector-url, global.proxy.tracer=zipkin, and tracing.enabled=false, and kiali.jaegerInClusterURL=jaeger-query-url (if kiali is enabled).  The new approach is to enable tracing and set addons.jaeger.name=jaeger (note, the jaeger resource name is not configurable on 1.1).
