[CATCHUP] - Integrate Proposal Fetching to Current Impl

[bfish713]

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

We should have all the building blocks where we can request and respond with proposals for prior views, and validate and update our storage. Now we need to hook up those functions into the implementation.

For the current (not dependency) version of the code we'll need to send the event to look up the proposal when missing, then spawn a task to wait for the response. On response received we should then call the handling logic and eventually emit a QuorumProposalValidated event

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