Add pipeline version support to frontend

[jingzhang36]

1. NewPipelineVersion page for uploading pipeline and version (replacing old upload pipeline dialog)
2. PipelineVersionList page for listing pipeline versions, e.g., when pipeline gets expanded in our home page
3. RunList page shows version reference as well as pipeline reference. In particular, old runs (created before version is introduced) show pipeline reference, while new runs show version reference.
4. Create run from versions instead of pipelines.
5. Delete version button
6. Clone run when run refers to version or refers to pipeline

The main structure looks good!
I put some nitpickings to hope improve readability.

I re-ran "npm run format". But still see formatting complaints...

Note setuptools is not a real failure, one integration test failed at the end of log.

[Bobgy]

I did a thorough review and left some comments, mostly nitpicking. This is good!

I think we are close to merge once these are addressed (and integration test is fixed).
