Support for OpenCTI platform clustering

[acodefella]

Is your feature request related to a problem?

Not exactly a pbm.

However, clustering OpenCTI platform is one of the best practices suggested by Filigran. This helps in number of ways, as it segregates pods for users (Frontend Cluster) and pods for data ingestion (Ingestion Cluster). More details available in Filigran documentation here : https://docs.opencti.io/latest/deployment/clustering/

This feature request would focus only on OpenCTI platform component. All other dependencies are taken care by HA options provided by sub-charts.

If this feature request is reviewed and accepted, I'm happy to send PR for this ASAP.

Describe the solution you'd like

Add labels to pod to distinguish between frontend and ingestion. Create services accordingly.

Describe alternatives you've considered

Addition of new deployment and associated services. However, this would result in lot of code duplication and lead to maintainability issues.
