[Stability] - Add polling for latest view sync cert

[rob-maron]

What is this task and why do we need to work on it?

We need to add polling for the latest view sync cert. We want to make sure that during view sync we have not only the current cert, but potential certs for the next view. It should stop polling when we've finalized view sync.

What work will need to be done to complete this task?
