Proposal: update the event table schema

[hawyar]

I propose a few changes to our events schema. The goal is to reduce unnecessary columns which greatly reduces our query execution time with Athena and overall maintain a clean structure that captures all the properties we need at the moment.

@elizyoung0011 has approved these new changes.
