Cobra by default lets us pass string values multiple times and uses the last one. This is confusing and was reported to be confusing on the `--blueprint` flag. Let's address it there with a new type that only allows a single value to be set. We might want to expand this to all string-type flags. Signed-off-by: Simon de Vlieger <cmdr@supakeen.com>
