Granular logging for sources, transforms and sinks by tracing span

[LucioFranco]

As a user, I want to be able to set customized logging levels for each stage of the pipeline to get a full picture of what each stage is doing. We currently support enabling logs by call site (aka by Rust module), but being able to enable them by tracing span would ensure that can set a log level for a given component and any shared modules that component is usig will also have the same log level.
