🆕 After install, set status on existing pull requests

[gr2m]

follow up for #97 (comment)

Currently the app does not set a status on existing pull requests. But I think it should. What’s important to consider is to throttle the requests, see https://developer.github.com/v3/guides/best-practices-for-integrators/

Before working on this I need to make sure that we have propper queueing in place for the requests to avoid hitting abuse rate limits

We have proper request throttling now, so let's do this.

Here is my plan:

• Start listening to both installation event and installation_repositories event.
• When action is deleted, just log
• When action is created, update all open pull requests for all repositories sent in the event payload (.repositories or .repositories_added keys)
• When action is new_permissions_accepted, update all open pull requests (for upgrades such as commit status -> check runs). The event payload has no .repositories key so we have to retrieve it first
