Add a global setting to never auto summarize

We have some reporting requirements that can involve pulling in hundreds of columns of data, yes we've suggested better ways to do this, but for some ingest feeds that's what came as the client requirement. This for one starts to get rather pokey, but it's extra annoying when PowerBI decides to summarize each field and you have to go in and tell it not to summarize for dozens of them.  

There should be a global setting to not summarize new columns you can toggle on and off once, like there's a pause updates feature.
