Make Table PUT API more intuitive

[keiono]

In current version, updating Table data requires the following steps:

1. Create new columns one-by-one
2. Prepare data to be PUT:
   • mapping key name in target table
   • mapping key in the data to be posted
   • Actual key-value pairs
3. Call PUT method

This is not intuitive. We need a simplified method to batch-update table.

The API has been updated to accept simplified document body:

{
    "data":[
        {
            "SUID": 1234,
            "col1": "foo"
        }
    ]
}

Also, it automatically creates new columns if it does not exists.

Limitation

Automatic column creation is limited to the following data types:

• String
• Boolean
• Number (Double)

If user needs to specify number types, he/she needs to create column before calling this PUT method.
