[Bug]: otel span names are too long

[codefromthecrypt]

What happened?

In other agent frameworks that have built-in opentelemetry, there are hand chosen span names. These are easy to read even if there are some times variables inside. The spans created by instrumentation in A2A at the moment are too verbose. For example "a2a.server.request_handlers.default_request_handler.DefaultRequestHandler.on_message_send"

Here's an image of a trace in otel-tui, which highlights the usability problem.
