Customize settings for Weekly Report

### Problem Statement

I get a weekly report from our app that usually includes a lot of dev issues at the top issues list, because we tend to have more of these than production issues. I'd like to be able to filter the issues that show up in that list to specific environments

### Solution Brainstorm

As an initial implementation, possibly just a setting for this specific config (should the weekly report include issues from env X). The weekly report settings already include "on/off" for each project. This could instead be a pick-list of environments to include in the weekly report.

One issue with that solution is that some people may not want to exclude dev issues from the metrics reports - though personally I don't care what's happening in dev so much, until it significantly affects my quotas.
