Running `make generate-crd-docs` in the root project or `make update-crdlist` in Documentation will run the crdlistgen tool. This tool rebuilds the Documentation/crdlist.rst file by looking at the pkg/k8s/apis/cilium.io/client package's CRD List. It will also scan the rst files of Documentation to see if the CRD is being used as a header anywhere to generate a link to it. Signed-off-by: Daniel Hawton <daniel.hawton@solo.io>
