delegate to the API instead. (will shave off roughly 3-4s every use)

Override resource_web_url to catch ResourceURLMissingError as there
is no "show" action for a CI/CD var

object pool. If the pool doesn't exist, it will create an empty pool
before attempting the fetch. This change adds client code as well as
specs to cover this behavior.
