Subject: [PATCH] DEV: Drop deprecated columns (#25640)

Since we just released 3.2, this is a good time to drop deprecated columns. This is a two-phase process. First we drop the columns, then we remove the ignored_columns declarations. Because of that I'm batching all deprecated columns for dropping here first. Once a full deploy is done we remove the declarations.
