Hopefully fixes#1991
I don't have N1 setup locally, so this is a blind shot–would appreciate somebody who has it set up to pull this and verify this fixes the issue, but as far as I can tell it should.
The gist is:
> Looking at the code, what you do is use the `search/users` endpoint to find users by email and taking the repos from there. You then load the repositories of the username, but we can't sort those by most-starred: "sort string Can be one of `created`, `updated`, `pushed`, `full_name`. Default: `full_name`" *([src](https://developer.github.com/v3/repos/#list-user-repositories))*
> What we could instead do is use the search API, which **allows us to search for repositories by a specific user and sort by most starred**. This is a tiny bit hacky, but works perfectly fine. E.g. this is the URL for my most starred repos: `https://api.github.com/search/repositories?q=user:mxstbr&sort=stars&order=desc`
Summary:
Adds two (very similar) plugins - Open Tracking and Link Tracking.
Both can be enabled via a button in the composer. Open tracking
inserts a tracking pixel right before send, and link tracking replaces
all links with tracked redirects. Both plugins use the new Metadata
service to store their open/click counts, and have backend servers to
respectively serve the pixel image or handle the redirects. Requests
also trigger a metadata update to increment the open/click counters.
Test Plan: Manual for now
