current implementation adding LogSpan with logger name

this was added in some early stages of implementation (in slf4j-bridge (slf4j v1), slf4j2-bridge (slf4j v2) was made based on slf4j-bridge) where there were changes from Zio1 to Zio2

Ideally there should be feature flag, which allow to disable it, configuration should be made in way, that there is possibility to add new features

there should be implementation for slf4j-bridge (slf4j v1) and slf4j2-bridge (slf4j v2)
