Make memory configurable from values for easier override?

Make configurable? Memory requirements are very application package and query patterns dependant.
Added Helm charts for deployment, based on
Multinode-HA, to allow for more convenient management.Created charts to simplify the deployment of a multi-zone Vespa application.
Architecture of the charts:
configserverwith high-availability support.configserverinitialization, leveraginginitContainers.Added a readiness mechanism for
configserver:These changes simplify the deployment process and ensure the proper sequence for starting components.
