What would you like to be added?

Currently the source for vsphere.conf is ConfigMap/Secret but it is sometimes more convenient to store the content in the filesystem of the node. The pod can mount this path with hostPath option, but it needs to be configurable in the helm chart options.

Why is this needed?

This configuration option will streamline bootstrapping process for the component, when creation of ConfigMap or Secret can’t be automated, but the filesystem access is present, so a file can be created on the node first.
