We limit rollbacks to 30 minutes. Currently we measure the difference in time between the end of the sync source's oplog and the rolling back node's oplog: https://github.com/mongodb/mongo/blob/955dfb45f2f67d2f4570912dbcddecbf3e7bb116/src/mongo/db/repl/roll_back_local_operations.cpp#L97-L108. We should really be measuring the difference between the common point and the end of the rolling back node's oplog.

While we are doing this, we should make the limit configurable.
