Improvement to DH feedback

[chloelee767]

Suggested features:

• Send a poll about the food quality to the bistro group every breakfast and dinner

Steps to take:

• Design the workflow
• Design the user interface (with mockups) of how such feedbacks are done
• Design the backend - how to store such data
• Code the feature

• @darrenlimweiyang to discuss with Dining Comm to check on requirements for poll.
  • First step - manually put poll on bistro group for a few days first.
