Summary:
Sequelize can sometimes return promises that will never resolve or
reject. We can wrap the promises we get back from sequelize in a
bluebird promise which gives us the ability to timeout these abandoned
promises. This way, we can track down issues in sequelize as well as
unblocking stuck sync loops.
Test Plan: Run locally, verify that timeouts occur
