feat(CSI-227): allow host networking via configuration

[sergeyberezansky]

TL;DR

This pull request introduces a conditional configuration to enable hostNetwork support for the csi-wekafsplugin Helm chart. The changes involve adding conditional checks in the templates to apply the hostNetwork settings based on the values provided.

What changed?

• Added conditional statements to controllerserver-statefulset.yaml and nodeserver-daemonset.yaml to apply hostNetwork settings.
• Updated security context constraints templates to allow host networking when the hostNetwork value is true.
• Modified port numbers in the nodeserver-daemonset.yaml to accommodate the hostNetwork setup.

How to test?

1. Set hostNetwork: true in the values.yaml file.
2. Deploy the Helm chart.
3. Verify that the necessary resources are deployed with the hostNetwork configuration.

Why make this change?

This change is motivated by the need to support host networking for specific environments where pod networking might be insufficient or problematic, such as Weka clusters running on top of Kubernetes. Allowing conditional hostNetwork configuration provides greater flexibility and control over the networking setup of the CSI driver components.
