I recently discovered that the metrics reporting to Google Cloud Metrics for the relays is actually working. Unfortunately, they are all bucketed together because we don't set the metadata correctly. This PR aims to fix that be setting some useful default metadata for traces and metrics and additionally, discoveres instance ID and name from GCE metadata. Related: #2033.
