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

[victorpablosceruelo]

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
If applicable, add screenshots to help explain your problem.

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.

This is sometimes a bug (Jenkins pipeline execution fails randomly), but I did not wanted to report it as a Bug because it is not happening always.
