Tracing: more eventbus and HTTP tags

[Olamshin]

Version

4.4.6

Context

According to the document here, the following span attribute should be present for HTTP server spans.

• http.scheme
• http.target
• net.host.name
• net.host.port

Absence of these attributes would mean OTel spans from vert.x may not be categorized as HTTP spans by a telemetry backend.

@tsegismont Yes, i can attempt this. Looks like the core changes would here? Any other tips would be appreciated!

Yes, I would start here. Then we need to make sure we don't break other tracing implementations

we should keep the actual names and translate them in vertx open tracing when it get the tags. if there are missing tags then we should add them using the same convention
