limits_not_recommended job from os-conf/22.3.0

This job is not recommended. Firstly, it blindly copies in a configuration file with no error-checking, potentially causing deployment failures. Secondly, it encourages the increase of system limits to work around broken BOSH jobs, when effort is better spent fixing the BOSH jobs (e.g. increasing `nofile` to get around a faulty long-running BOSH job that leaks file descriptors and finally fails).
