Exclude dags from DAG View using tags

[match-gabeflores]

We can filter for specific dags to see by tags ("marketing"). Great.

I would like the ability to show everything except a certain tag ("analytics"). the reason is because we have about 30 tags. a couple of them have 100+ dags.

I don't care about having another filter textbox in the UI, if i could just do something in the URL so i can bookmark it.

currently, i have a bookmark where i list them all in the url but we add new tags, i have to manually update this bookmark and it's not obvious whenever new dags are added.
