fix: add-threading-instrumentation

[poshinchen]

Description

We recently updated the agent calls with threading, this causes opentelemery fails to propagate context and result in creating multiple traceIds instead of one.

Adding opentelemetry-instrumentation-threading > ThreadingInstrumentor to allow context propagation between threads. And the package itself is pretty light so we can include them while installing the sdk-python.

Can we add test coverage to ensure that this regression doesn't occur again in the future?
