Expose logging level input

[uhari03]

Similar to how secrets-store-csi-driver exposes the logging verbosity: https://github.com/kubernetes-sigs/secrets-store-csi-driver/blob/0d9652974f7665a34f83f8288bf7dadc16401606/charts/secrets-store-csi-driver/values.yaml#L200

Can we expose similar options here?
Otherwise we are forced to fork away from the helm chart.

When installing via EKS Addon, here's the logging arguments:

$ kubectl describe daemonset aws-secrets-store-csi-driver-provider -n aws-secrets-manager | grep -A5 "Args:"
    Args:
      --provider-volume=/var/run/secrets-store-csi-providers
    Limits:
      cpu:     50m
      memory:  100Mi
    Requests:

$ kubectl describe daemonset secrets-store-csi-driver -n aws-secrets-manager | grep -A5 "Args:"
    Args:
      --v=5
      --csi-address=/csi/csi.sock
      --kubelet-registration-path=/var/lib/kubelet/plugins/csi-secrets-store/csi.sock
    Limits:
      cpu:     100m
--
    Args:
      --endpoint=$(CSI_ENDPOINT)
      --nodeid=$(KUBE_NODE_NAME)
      --provider-volume=/var/run/secrets-store-csi-providers
      --additional-provider-volume-paths=/etc/kubernetes/secrets-store-csi-providers
      --enable-secret-rotation=true
--
    Args:
      --csi-address=/csi/csi.sock
      --probe-timeout=3s
      --http-endpoint=0.0.0.0:9808
      -v=2
    Limits:

Verbose level 5 seems way too noisy to be a default!
