[kfp sdk] Added examples for ArtifactLocation, ResourceOp, VolumeOp, and Sidecar.

[eterna2]

Recent PRs have added quite a few new features to kfp sdk, so I have updated the samples/basic with the following examples:

• artifact_location.py on how to config artifact location in the pipeline workflow template
• sidecar.py on how to add sidecars to containerOp in a pipeline

NOTE

As requested by @hongye-sun in #1064, I have added an example for my PR. But I've also added a
few more example for recent PR too.

Hi @eterna2. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

These ResourceOp and VolumeOp samples are also under samples/resourceops/, along with other samples on VolumeOps and VolumeSnapshotOps.
Maybe it's better to rearrange those, e.g. create the directories samples/volumes/ and samples/snapshots/ or something like that.

[eterna2]

Ah, I didn't realize that. Must have missed them. Cuz the other subfolders looks like extension samples - I assumed all dsl samples are in basic.

I will just remove them and just leave artifact location and sidecar.

I will just remove them and just leave artifact location and sidecar.

Sure, I'll make another PR rearranging them then. Thanks!
