Point the stackdriver_exporter modules to the actual PR commit (prometheus-community/stackdriver_exporter#477) so the build no longer depends on a local filesystem layout. Signed-off-by: Arthur Silva Sens <arthursens2005@gmail.com> Made-with: Cursor

Summary
Adds a new
otelcollector/Go module that implements the prometheus-collector-bridge interfaces, enabling the stackdriver exporter to run as a native OpenTelemetry Collector receiver.This is a proof of concept for the upstream proposal prometheus/proposals#69, which aims to embed existing Prometheus exporters inside OTel Collector distributions.
Design decisions
Separate Go module (
otelcollector/): Keeps all OTel Collector dependencies (bridge, collector SDK, pdata, etc.) out of the main module's dependency tree. The parent module is imported via a localreplacedirective.Single long-lived registry: The bridge expects
ExporterLifecycleManager.Start()to return one*prometheus.Registrythat it periodically gathers from. We create it once at startup and register aMonitoringCollectorper resolved project, rather than the per-request registries used by the HTTP handler.Full config parity: Every CLI flag (except deprecated and web-server-specific ones) is mapped to
exporter_configvia mapstructure tags.
