RHAIENG-1603: Introduce new build-args for konflux build

Description

To minimize code conflicts between Dockerfile.* and Dockerfile.konflux., and to avoid having specific changes for Konflux, we can customize those changes into build-args. These build-args can be clearly separated between upstream and downstream build arguments. By doing so, Dockerfile.konflux. will become more similar to the original upstream Dockerfile., while still having their own specific parameters defined separately in their own build-args/.conf.

How Has This Been Tested?

gmake test => ✅ All Dockerfiles are in sync.

Self checklist (all need to be checked):

• Ensure that you have run make test (gmake on macOS) before asking for review
• Changes to everything except Dockerfile.konflux files should be done in odh/notebooks and automatically synced to rhds/notebooks. For Konflux-specific changes, modify Dockerfile.konflux files directly in rhds/notebooks as these require special attention in the downstream repository and flow to the upcoming RHOAI release.

Merge criteria:

• The commits are squashed in a cohesive manner and have meaningful messages.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work

You can still manually trigger a test run with /test all

Hey Vath, these changes look good. However, these files are synced from konflux-central this is the notebooks builds folder.
Once we decide on the RHOAI version to apply them to, we can update the files directly there (in the RHOAI release branch and main), and then sync them back here.

@atheo89 does that mean I have to submit another PR to konflux-central for .tekton/* ? And does it get synced manually/automatically?

[atheo89]

@ysok exactly. Looks after the push commit the changes sync automatically on the components repo. For more details check here: https://github.com/red-hat-data-services/notebooks/blob/rhoai-3.0/.tekton/README.md

[ysok]

This PR is good to merge, the konflux.*.conf files are here in repository, but won't get used until I made changes to .tekton files in konflux-central repository.

I'll create another separate PR for konflux-central, and it should sync .tekton files back to this repos, so it can make used of this konflux.*.conf
