Override tracing preferred service name and pin to dynamic config

[amarziali]

What Does This Do

This PR allows to override the default service name when the user is not supplying one explicitely. This service name is then use as a default one for span not having one set (typically local roots) and it's pinned to the dynamic config current snapshot for other further usages.

The entry point for overriding (if possible) this service name will be through the already existing SpanNaming object
