Disable Elastic APM Default Tracer that would otherwise gather metrics
and send them on localhost even if no tracing backend was specified.

Fix #2610

  • I added CHANGELOG entry for this change.
  • Change is not relevant to the end user.

I don't think the change is relevant as I don't see anyone using the default metric gatherer without enabling tracing. However feel free to edit it if you think the new behavior is considered breaking changes.
The worse case scenario is: someone is using the default gatherer to gather Go Metrics without having tracing enabled. As far as I understand it, this is undocumented and unsupported.

Changes

Disable Elastic APM default tracer on initialization

Verification

Start thanos with ELASTIC_APM_LOG_LEVEL=debug and ELASTIC_APM_LOG_FILE=stdout. Elastic APM does not try to gather and send metrics anymore.

Yuck, thanks for this! LGTM. Could you please rebase on master? I think we should not note this as a breaking change since this was never documented and there is a proper way to load a tracer configuration into Thanos that it supposed to be used.
