Persistent storage doesn't work

[richarddli]

I tried to deploy a mongoDB. kubectl describe pod mongodb says:

` FirstSeen LastSeen Count From SubObjectPath Type Reason Message

---

5m 29s 22 {default-scheduler } Warning FailedScheduling PersistentVolumeClaim is not bound: "todo-db-persistent-storage-todo-db-0"`

Adding some additional context I received (internally found issue):

Reproduction steps:

1. Clone out TODO
2. Forge deploy

This looks like a case where there is no default storage class for the instance. We should probably install one.
