APM span error is not highlighted when otel.status_code = "ERROR"

[damikun]

Summary of the problem
The APM trace view does not highlight errored span in trace view in case error is reported over Opentelemetry protocol. (otel.status_code = "ERROR"). This is related to trace SPAN error !

Telemetry data flow: NetCore > OpentelemtryCollector > ElasticAPM server all over otel-protocol.

State:

• Some span is errored
• Span contains otel.status_code = "ERROR"
• The error is visible only on span detail not in Trace view
• Error is never highlighted and in span view it has only gray color.
• This span also contain error log from logging system that is visible but also not highlited

Requirement:
Span errors must be in trace view visible for errored Span similar as status code errors or system exceptions errors...
