[Dev]: Operations filtering

[TylerBloom]

Unmet Need:

When a user submits a sync request for a tournament, we must verify that the changes that they are submitting for that tournament are allowed to be submitted by them. In other words, players can't submit operations for other players, judges can't submit admin operations, etc. However, if they submit a known operation, they are ok. So, this check should happen after the tournament manager creates the sync processor but before it is processed.
