What is this PR about? / Why do we need it?

Add a nodeComponentOnly parameter to helm chart.

What testing is done?

Here are helm template results with and without setting nodeComponentOnly=true, as well as the diff (as textfiles because gists don't support yaml):

nodeComponentOnlyTemplate.txt
defaultChart.txt
diff.txt

Also deployed the driver with this setting:

helm upgrade \
  --install aws-ebs-csi-driver \
  --namespace kube-system \
  $HOME/workplace/aws-ebs-csi-driver/charts/aws-ebs-csi-driver \
  --values "$HOME/workplace/tools/driver-testing/driver-up/custom_values.yaml" \
  --set nodeComponentOnly=true

Release "aws-ebs-csi-driver" does not exist. Installing it now.

For better name. Leaning towards nodeDriverOnly

Edit: Connor proposed nodeComponentOnly, I'm a fan.
