AWS bedrock-runtime instumentation for botocore

[xrmx]

This is a tracking issue for the implementation of tracing for Converse and InvokeModel APIs and their respective streaming version. Big difference between the two APIs is that converse is the same for every model while InvokeModel requests and response are different for each model.

• converse Basic instrumentation for Bedrock runtime Converse api #3161
• invokeModel botocore: add basic handling for bedrock invoke.model #3200
• converseStream botocore: add basic tracing for bedrock ConverseStream #3204
• InvokeModelWithStreamResponse botocore: add basic tracing for Bedrock InvokeModelWithStreamResponse #3206
• error handling for streaming botocore: handle exceptions when consuming streaming versions of bedrock APIs #3211
• close span also when closing stream calling __wrapped__.close()
• server attributes (generic for botocore?)
• events
• metrics
• tool calls
• proper semconv attribute for cloud region
• http stable semconv opt-in support
• more models for InvokeModel* ?
• other bedrock runtime apis?
