ubi8 docker image for Terraform installs packages from centos when there are better options in rh repositories

Describe the bug
When generating ubi8 docker images, we are installing packages from centos instead of using the ones available at Red Hat.
Although most of the times we do this it is not really a problem, if they are incompatible in some way, we'll suffer that incompatibility.

To Reproduce
Steps to reproduce the behavior:
Just generate the docker image in folder
common/jenkins-agents/terraform/docker/Dockerfile.ubi8

Expected behavior
Packages should be installed from RH repositories when available

Screenshots

Affected version (please complete the following information):

• OpenDevStack [e.g. 4.x, master]

Log Output (ensure to remove any confidential information like tokens, project names, etc.

Additional context
Add any other context about the problem here.

When doing this, take into account that some packages are not available at Red Hat repositories, so we might need to determine which ones need to be installed from Centos repositories.

Start with common/jenkins-agents/terraform/docker/Dockerfile.ubi8 and generate the UBI8 Docker image to identify packages currently sourced from CentOS. Check which of those packages are available from Red Hat repositories, retaining CentOS sources only where necessary. Done means the image builds successfully and uses Red Hat packages whenever available.
