Add Merchant-Specific Terms

Each waitlist merchant can choose to specify any unique terms or conditions on the "Join Waitlist" modal.

A waitlist advisement example that says 'The Business will only hold y
      our spot for 15 minutes after your table is ready' on the 'Join Waitlist' modal.

These features can be added by specifying the merchant.waitlist_advisement field.


    "merchant": [
      "waitlist_advisement": {
          "value": "We can only hold your table for 15 minutes once it is ready."
