Run dispatchProcesses on Heroku

[jeffm2001]

Description

This adds a command for triggering dispatchProcesses on a Heroku install. When triggered, it runs the following jobs:

• erroredMessageSender,
• handleIncomingMessages,
• checkMessageQueue,
• fixOrgless,
• clearOldJobs,
• updateOptOuts

To use configure the Heroku Scheduler add on and add a job running every 10 minutes with the command yarn prod-heroku-dispatch.

Unfortunately, 10 minutes is the most frequent scheduling the heroku add-on allows, while AWS is set to dispatch every 5 minutes. Although, maybe every 10 minutes is good enough. If not, I may look into other options like a custom clock process or a worker using Bull.
