See which segments, dashboards uses an evar

[#1]

I want to delete a Processing Rule that is setting an evar but I want to know what Segment and Dashboard is using the evar first so I can notify the organization of the changes. It would be nice to have a view, for example under Admin > Conversion Variables, where I can see what Segment or Dashboard is using an evar.

On that note, add in scheduled reports, report builder queries and data warehouse reqeusts.
