order lifecycle about roti

[SharangP]

for now, we are adopting the quota model:

• vendors will list their quotas for each item
• customers see the remaining amounts in each product when the vendor page loads
• when the order button is clicked, we check whether the order can be placed without exceeding the quota in a transaction
