Create a custom devfile sample

# Create the configmap with sample json config
oc create configmap getting-started-samples --from-file=samples.json -n openshift-devspaces

# Label the configmap for use by dev spaces
oc label configmap getting-started-samples app.kubernetes.io/part-of=che.eclipse.org app.kubernetes.io/component=getting-started-samples -n openshift-devspaces

Remove default samples
