Refactor eventgate-analytics to eventgate
This will allow for multiple service deployments using the same chart.
- Uses wmf.releasename as the service and app name labels.
- EventGate app specific conf and stream-config is now fully in values.yaml. These should be overridden in production with service & release specific values files.
- Slightly rename configmaps and volumes for better consistentency
eventgate-analytics will be removed in a future patch
