chore(components): Delete deprecated dataproc components

[chensun]

These deprecated components don't build in post-submit cloud build as their Dockerfile is based on Python 2.7
https://pantheon.corp.google.com/cloud-build/builds/2ff01688-9b36-4699-866a-86cbcd46ba14;step=20?project=ml-pipeline-test

Confirmed with @Ark-kun that it's fine to delete the code.

Partially fixes: #5007

Got catch! following this I found a couple more references that need to be deleted.
