Add more metadata tracking examples - notebook and pipeline

[Jeffwan]

1. Metadata by default is enabled for pipeline project. We want to give more examples to users.
2. In other type of workloads, like model training, we want to add more examples (this has been added I think - double confirm or update the example if there's API changes).

1. What type of Metadata examples we want to give? From the repo, I saw that we have this example. But for this example, we can only see the Metadata in the Artifacts store. In my opinion, we can add more metadata notebooks to bootstrap kubeflow pipeline. And our user should be able to see artifact visualization retrieved from every run's metadata.
2. For other workloads, I found they have already been added to the repo, I'll sync with you and go head to confirm if they're compatible with kubeflow 1.0 currently.

WDYT @Jeffwan

From my part, I think current Metadata example is good enough, do you have any idea about other examples in metadata area?

I can give more examples on metadata, but it will be similar to the metadata example's Real World Example. Thus, I'm not sure if this is necessary. @Jeffwan

Check my original asks, I think second one is ok. What about the first one, pipeline metadata tracking? @PatrickXYS

[PatrickXYS]

I'll be creating a real-world example with metadata artifacts visualization.

@PatrickXYS for first item or second? If that's second, as we talked, we don't plan to add extra ones, right?

[PatrickXYS]

What I mean is write an example for lineage explorer tracking as we talked, wdyt? @Jeffwan

An example below:
