Add the realtime inference components

[yatharthranjan]

Is your feature request related to a problem? Please describe. These components include KSQLDB (both server and cli), model-builder (can run on a CRON schedule), model-invocation, RADAR-Backend Intervention monitor or RealtimeInference Consumers, a Feature DB (postgres), JDBC connector to sink the features to the db, optional grafana dashboard to view the aggregated data and inference results for monitoring.

Describe the solution you'd like Look at the distributed-dcompose for these components in plain docker-compose stacks. This can be used as a starting point to move them to helm. Will also require adding new charts to radar-helm-charts repo.

Describe alternatives you've considered N/A

Additional context Add any other context or screenshots about the feature request here.

Slight modifications to this issue:

• the grafana dashboard and JDBC connectors are already present.
• I'm not sure whether the ksqlDB cli needs to be included, since the same can be achieved by running exec in the server container.
