OAS: add generic artifacts routes

[isinyaaa]

Closes: #369

Description

Implements generic artifact routes as proposed.

There will be a follow-up to add new methods to the Python client as well.

How Has This Been Tested?

Updated unit tests to cover new core methods.

Merge criteria:

• All the commits have been signed-off (To pass the DCO check)

• The commits have meaningful messages; the author will squash them after approval or in case of manual merges will ask to merge with squash.
• 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.
• Code changes follow the kubeflow contribution guidelines.

If you have UI changes

• The developer has added tests or explained why testing cannot be added.
• Included any necessary screenshots or gifs if it was a UI change.
• Verify that UI/UX changes conform the UX guidelines for Kubeflow.

Hi @isinyaaa, I left just one comment on the goverter definition as I am not completely sure the result would be the expected one. Other than that, it looks great to me!

I'm so glad all the suggestions so far have cut down the patch size tremendously :) thank you so much @tarilabs @lampajr for the care

thank you again @isinyaaa
/lgtm

focusing on the Go side, anything 👀 worth noting @Al-Pragliola ?

I see the new routes and I don't see changes to the path of the existing REST apis, beyond that

	if artifact == nil {
		return nil, fmt.Errorf("invalid artifact pointer, can't upsert nil: %w", api.ErrBadRequest)
	}

so I'm good with merging asap, I just wanted to double-check this understanding
