Resume connector change stream using the timestamp of the first event

[Kerkesni]

There is currently a lag between when a bucket has a workflow set and when its events get picked up by the oplog populator.

This can cause issues as we might miss the first oplog events of the bucket.

We start the change stream from the first event that triggered the creation of the connector using startup.mode=timestamp to avoid loosing the first events.

Issue: BB-471
