Dear whiskers. I am about to merge this PR [1]. This is to specify a different limit with the system default for a certain namespace. With this change, we can configure a bigger limit for a certain namespace without altering the system-wide configuration that impacts all systems. It is backward-compatible.
Since it has been open for a long time, I would merge it based on silent consent. Please feel free to share your opinions and suggestions. [1] https://github.com/apache/openwhisk/pull/5229
