[mwarkentin]

Added the topics to validation in a separate PR so that we can deploy this, then do https://github.com/getsentry/ops/pull/4967, and then finally roll out the rest of this PR.

#2930

[lynnagara]

You may want to move this line (and the distributions equivalent) into a separate PR. So we create the topics first and have them in topics.py but then start actually producing to them later.

removing that now, and then I'll merge and then we can do the ops PR
