Description

The host telemetry is very noisy. E.g. while running for 30 mins one host generated ~2300 traces (x2 spans) with various Azure storage operations related to host internals.

There should be a way to disable it without disabling trigger telemetry.

Can share some semi-internal Azure SDK suppression tricks or brainstorm alternatives.
