Description

This PR sets DD_INSTRUMENTATION_TELEMETRY_ENABLED in our app and DD_APM_TELEMETRY_ENABLED in the DD agent to false. According to Datadog support, and their documentation, those two env vars are set to true by default, but the federal govt datadog URL does not support those features.

When those are set to true, our DD agent attempts to make calls to the telemetry endpoint, which doesn't exist, causing 404 throttling errors in our logs.

For reference: https://docs.datadoghq.com/tracing/configure_data_security/?tab=environmentvariables&site=gov#telemetry-collection

issue #2111

How Has This Been Tested?

Successful perf deploy here: https://github.com/department-of-veterans-affairs/notification-api/actions/runs/12399618902

I deployed this change to perf and those throttling error logs lines are now gone.

The deploy finished at around 2:15pm ET and those log items stopped showing up at around 2:19pm ET.
