Setup CI infra for testing odo on Podman

[rm3l]

@## User Story
As an odo developer, I want to set up CI infra So that I can reliably run odo tests using Podman as backend and be confident with my code changes.

Acceptance Criteria

• It should not keep a long-running VM; instead, it should spin up VMs (with Podman) on the fly and destroy them once the tests are done
• It should pass all tests added in Integration tests for odo dev running on podman  #6332, using the test-integration-podman Make target
• Add a script to reproduce the env.

Just to be sure, we don't want a long-running VM for this test,

• we want to create and delete VMs on the fly, for each test run.

Yes, ideally. That's what we concluded in the Cabal call on Nov-8.
You can start with on-demand VMs for now, and we'll see how long it takes to start a VM on IBM Cloud.

It would be interesting to try to run the tests with a GitHub action, using a ubuntu system (runs-on: ubuntu-latest), as this image contains podman
