Dogfooding :: Impossible to build che-code docker image due to reaching the maximum amount of opened files

[vitaliy-guliy]

Describe the bug

I'm trying to build che-code docker image on the dogfooding instance, but the build continuously fails with EMFILE: too many opened files

Che version

next (development version)

Steps to reproduce

1. Create a workpace from https://github.com/che-incubator/che-code
2. Open build/dockerfiles/linux-libc.Dockerfile, remove all the content related to testing ( Lines between ### Testing and # Store the content of the result )
3. Open a terminal and run the build with podman build -f build/dockerfiles/linux-libc.no-test.Dockerfile -t linux-libc-amd64 .

Expected behavior

The linux-libc-amd64 image should be successfully built.

Runtime

OpenShift

I was able to build che-code docker image on the dogfooding instance:

I've increased ulimit for open files directly in the command to get it working

Exactly what I'm doing in the devfile https://github.com/che-incubator/che-code/blob/switch-to-udi/devfile.yaml#L107

To avoid providing this option to all podman commands I think we have to configure it by default like here containers/podman#6093 (comment)
