Fix of some minor bugs when using the driver manifest and update helm chart versions

[elivlo]

Fix of some minor bugs when using the driver manifest or helm chart. This should also create a new helm release 3.0.1 with the current app version 3.0.0.

Description of changes:

• The manifest.yml was missing a line break between two resources
• Update of the app version in the helm chart to 3.0.0
• Add a third empty option to the helm value node.metadataSource description as a feasible option (csi will take the name of the kubernetes node)

Testing performed:

I have set up a cluster in a private Cloudstack instance with Talos. This cluster works with the current version (3.0.0) of the csi plugin. I made some config overrides in the helm chart values by adjusting them manually. These overrides were done with terraform and can be reproduced:

resource "helm_release" "cloudstack_csi_driver" {
  name      = "cloudstack-csi"
  chart     = "https://github.com/cloudstack/cloudstack-csi-driver/releases/download/cloudstack-csi-2.0.3/cloudstack-csi-2.0.3.tgz"
  version   = "2.0.3"
  atomic    = true
  namespace = "kube-system"
  set = [
    {
      name  = "cloudConfigData.global.api-url"
      value = var.cloudstack_api_url
    },
    {
      name  = "secret.create"
      value = true
    },
    {
      name  = "secret.enabled"
      value = true
    },
    {
      name  = "controller.image.tag"
      value = "3.0.0"
    },
    {
      name  = "syncer.image.tag"
      value = "3.0.0"
    },
    {
      name  = "node.image.tag"
      value = "3.0.0"
    },
    {
      name = "node.metadataSource"
      value = ""
    }
  ]
  set_sensitive = [
    {
      name  = "cloudConfigData.global.api-key"
      value = var.cloudstack_api_key
    },
    {
      name  = "cloudConfigData.global.secret-key"
      value = var.cloudstack_secret_key
    }
  ]
}
