Add otel compliant spans to external http spans

[bizob2828]

Description

We are trying to align on gaps with our span attributes and OpenTelemetry specification. With that being said we are missing http.request.method and server.address.

Acceptance Criteria

All external http spans(non-streaming and streaming) should provide http.request.method and server.address.

Additional context

Note: These are not the segment attributes. Spans get created from segments when a transaction ends here

• Ruby PR
• The http spans attributes are created in the DatastoreSpanEvent and StreamingDatastoreSpanEvent
• http.request.method is the same as http.method
• server.address is the URI of http.url
• server.port port of http.url
