Golang heap metricsetedit

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

The heap metricset of the Golang module collects the memstats information from the expvar API.
