Reviewer - Intermediate State for each step in review

[sivaa]

• Currently we have only review_status. It is used to choose the final decision
• We need to have reviewing_step field where review can update what step they are currently in(Waiting for content, Speaker not reachable, Requested more details for the Speaker, etc...).

@sivaa This will be helpful. I think we just need to add state in DB which will resolve this right ?
