Summary

1. This PR rewrites the preload / present operations into one operation to solve some queueing problems. The operation will now figure out what it has to do based on how it is initialized.
2. This PR changes cancelation behavior. Before if you sent a present, then another present, the manager would try to cancel previous ones. Now they will be queued and the dev can cancel previous ones if desired.
3. This PR fixes strange deletion behavior. Before if a delete came in while a preload / present was happening, the manager would try to delete choices from the upload. Now it will wait until the delete operation comes around and delete at that time. This allows proper behavior around preload -> present -> delete situations.
