Occasional non-responsiveness of app

[glencbz]

Occasionally, call home fails to respond to user requests. This triggers a CRITICAL error from Heroku and Heroku restarts the process. The most likely cause seems to be that the hourly jobs schedule multiple Promises simultaneously, causing the user request not to be responded to in a timely manner.

There are multiple possible fixes:

• Run the jobs in another piece of infractructure (e.g. another dyno or lambda)
• Run the jobs in another process/thread
• Schedule the promises in series instead of in parallel
