Tn/add groups

[TylerNoblett]

I've added a user group feature that allows system admins to create groups of users, and then system admins or operation admins can assign those groups to an operation. If a user is assigned to an operation via a group AND individually, the greater of the permission levels of the two will be granted.

Here's a video showing the system admin view:

Sorry for the long, long time it took to get through this.

Overall, this looks fine. I think we can improve the add users to group query, and the deleting users from group query (into, hopefully, a single query, or at worst a group of queries (select from users, then delete where in) ). Personally, I think it's also worth dropping the pagination support on the backend for groups, and maybe just doing front-end only pagination.

With those two queries (and optionally the pagination) fixed, I think we'd be in a good place to merge.

Thanks for reviewing it Joel! No worries; it was pretty long 😬 I've modified both queries and am going to take a look at pagination right now!
