Deploy fork of eventrouter to capture Events in Loki

Capture Kubernetes Events via eventrouter and punt these into Loki using
Promtail, along with a simple pipeline stage to extract a given event's
namespace out of the metadata for easier filtering.

This image is required because the RHEL ones are not public.
