• Variables and other changes are documented in the README.md
• Title of the PR starts with chart name (e.g. [artifactory])

What this PR does / why we need it:
currently the service generated from artifactory service creates a service with name: artifactory-ha.fullname. the artifactory-node-statefulset.yaml creates a spec.serviceName as artifactory-ha.node.name. the service specified in the statefulset needs to align, particularly when addressing pods directly in kubernetes DNS : https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/

this pr changes the service creation to have the same name as specified in the node statefulset spec.serviceName

Which issue this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close that issue when PR gets merged): fixes #
none

We decided not to implement this change as this might have impact on our current deployments.
In addition, the node sts should not be used anymore as only primary sts is in use.
