otel:
  sdk:     
    disabled: ${ONAP_SDK_DISABLED:false}
    south: ${ONAP_TRACING_SOUTHBOUND:true}   
  instrumentation:
    spring-webflux:
      enabled: true

1. onapotel.sdk.disabled: enable/disable tracing all toghether
2. otel.sdk.south: if ONAP_SDK_DISABLED is false then we can enable/disable southbound tracing
3. otel.instrumentation.spring-webflux.enabled: if ONAP_SDK_DISABLED is false we can enable/disable northbound tracing

...

So we can have the following combinations:

Tracing	Northbound	Southbound	Flags
			ONAP_SDK_DISABLED=true
			ONAP_SDK_DISABLED=false; ONAP_TRACING_SOUTHBOUND=true; OTEL_INSTRUMENTATION_SPRING_WEBFLUX_ENABLED=true
			ONAP_SDK_DISABLED=false; ONAP_TRACING_SOUTHBOUND=false; OTEL_INSTRUMENTATION_SPRING_WEBFLUX_ENABLED=true
			ONAP_SDK_DISABLED=false; ONAP_TRACING_SOUTHBOUND=true; OTEL_INSTRUMENTATION_SPRING_WEBFLUX_ENABLED=false
