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 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.

Disable Elastic APM default tracer on initialization
Verification
Start
thanoswithELASTIC_APM_LOG_LEVEL=debugandELASTIC_APM_LOG_FILE=stdout. Elastic APM does not try to gather and send metrics anymore.
