On recent OCP 4.20 buids, the containes seem to have tighter limits on max open files (ulimit -n) than previous OCP version (1024 vs 1048576)

This breaks existing applications.

This seem to break things, specifically,  I have noticed this while testing the Serverless Operator, its kourier-gateway crashes due to its inability to open new sockets even during parallel e2e test runs, not just performance tests)
