Add possibility to configure keda autoscaler for hazlecast and management-center

I would like to have the possibility to scale up hazelcast and management center based on keda crons

The issue does not name files or tests. Start by locating the Helm chart templates and values for Hazelcast and Management Center, then review how autoscaling resources are currently configured. Done means both components can be configured for KEDA cron-based scaling, with the expected chart checks or tests passing.
