DropletForbiddenAsNotFound is a special case due to the CF CLI expecting the error message "Droplet not found" exactly instead of the generic case https://github.com/cloudfoundry/korifi/issues/965.

LogAndReturn logs api errors at the info level and other errors at the error level since api errors are expected recoverable conditions.

NewUnknownError creates an UnknownError.

UnknownError is a generic wrapper over an error Korifi cannot recover from.
