Update non-form data of an Order (data that is exposed in Anduin master dashboard):

• Custom ID
• Metadata
• Close (Move the Order to a different Close)
• Tags
• Custom columns data

Note: metadata field that does not appear in the body params will be kept intact. To remove a metadata field, supply it with empty value (""). For example, with the current metadata as {"Oppotunity ID": "ID123", "Client Name": "John Doe"}. An update with metadata field as {"Partner ID": "ABC-VC", "Client Name": ""} will result in the following metadata {"Oppotunity ID": "ID123", "Partner ID": "ABC-VC"}. The same update behavior applies to custom columns data.
