(bug) Tracing only initializes when specifying endpoint through config

[hairyhenderson]

Observed behaviour

After #2482 and #2485, tracing won't initialize unless the openTelemetryOtlpEndpoint config entry is set. When I'm using OTEL_EXPORTER_OTLP_ENDPOINT instead I'd rather not have to specify it in the configuration as well.

Expected Behavior

Tracing should be disabled via OTEL_SDK_DISABLED=true, otherwise it should be enabled by default.

Steps to reproduce

Well I tried - either way I'm going to take this on, it's a simple fix 😉

#2579 should solve this 🙂
