ref(ch-upgrades): create dist tables functionality

[MeredithAnya]

Each time we run the series of these pipelines (fetcher, replayer, comparer) we first have to bring up nodes from backups and have our test clusters to work with. Doing the backup will restore the local tables, along with the data, but usually the dist tables are not backed up (if we change our backup process maybe we can change this) but as of now SRE folks would have to manually create the dist tables.

This aims to save the schemas of the dist tables during the fetching process, and when replaying for the first time we should be downloading the schema and using it to create the tables.

I tested this locally with my own gcs bucket
