Build images on CI for e2e tests

What needs to be added?

As a quality engineer, I want to add functionality for e2e tests to actually build images for odo deploy and odo builld-image on CI (prow / IBMCloud).

Why is this needed?

With this, we will be able to completely cover the e2e scenarios.

For IBM Cloud pipeline, I created a Dockerfile that contains podman and golang for executing test, to build Dockerfile present in test/example/nodejs

• when running the image with normal user (tester) fails with

Error processing tar file(exit status 1): potentially insufficient UIDs or GIDs available in user namespace (requested 0:12 for /var/spool/mail): Check /etc/subuid and /etc/subgid if configured locally and run podman-system-migrate: lchown /var/spool/mail: invalid argument

• when running the same image with root user fails due to SELinux

error running container: error from /usr/bin/crun creating container for [/bin/sh -c npm install]: mount `proc` to `/proc`: Operation not permitted

For prow/OpenShift-ci

Created a test on prow building a simple alpine image with a podman image, link to test It fails with

potentially insufficient UIDs or GIDs available in user namespace (requested 0:42 for /etc/shadow): Check /etc/subuid and /etc/subgid if configured locally: lchown /etc/shadow: invalid argument
