  We are being rate-limited by GitHub

  GitHub Apps use the installation's minimum rate limit of 5,000 requests per hour. Organization installations with more than 20 users receive another 50 requests per hour for each user. Installations that have more than 20 repositories receive another 50 requests per hour for each repository.

  I've added the dark feature "dvcs.connector.pr-synchronization.disabled" and will remove it tomorrow. The rate limits should be okay by then.

  After stopping GitHub polling, it seems we're not rate limited anymore. FLOE-535 is showing the merged PR now.

  @@Justin Obara could you confirm everything is okay? It seems it might take up to 60min to get a PR reflected in JIRA (if we're not rate limited).

  I also updated JIRA to version 7.7.1 and it might help with that (as there are some fixes for DVCS in it).

  It seems all PRs synced. I cannot see any errors related to GitHub since the JIRA instance was restarted a few days ago.
