Subject: add otel instrumentation (#581)

this change adds OTEL tracing to a few places

* Top-level application lifecycle (config/init/cleanup, main loop)
* http.sys requests

it also brings some otlptrace optimizations and dynamic configuration of tracing. OTLP tracing is currently always disabled
