Configuring just before we start the service seems to avoid permissions issues on Windows VMs. We did not see this issue on the Hull gateway machine with the relay listener.
These flood the logs with request traces from the monitoring transports. We only need to know if the monitoring transport fails.

Description
We disabled/removed opentelemetry with azure monitoring in the prep for the Hull test-run as we were seeing permissions errors and nothing else in the review env gateway logs.
We didn't see this behaviour in Hull when we configured a service to use opentelemetry (OTEL) as a test.
This PR re-adds the OTEL configuration as late as we can before starting services.
It also suppresses a lot of noise which comes from OTEL and azure monitoring as this fills the logs with unhelpful messages.
Tested on review env gateway.
