Web UI for the /integration/installations API endpoint


As an integration author, would be interesting to have a web UI with the list of installations of our Integration, just like what’s available on https://developer.github.com/v3/integrations/#find-installations, with the webhook delivery history for each installation.

We use the existing WebHooks to replicate this info in our database and display this info on our admin panel, but once or twice in a lifetime our app can fail and lose the details of a specific installation, and having a UI on GitHub (as the original source for this data) can be helpful when debugging and inspect that data.
