string format - Support for Conditional Replacements

[arindamghoshal]

Required Functionality
Construct string values based on conditional replacements as part parsing a parametric format string

Proposed Solution
Support for Ternary conditional operator as part of parametric format string. Something like this -

"productId": {
  "type": "string",
  "format": {
    "format": "{productType}_{IF({productType}=='alphabet', {alphabets}, {digits})}",
    "arguments": {
      "productType": {
        "type": "string",
        "categorical": {
          "alphabet": 1,
          "digit": 1 
        }
      },
      "alphabets": {
        "type": "string",
        "categorical": {
          "abc": 3,
          "def": 5,
          "ghi": 2
        }
      },
      "digits": {
        "type": "string",
        "categorical": {
          "123": 3,
          "456": 5,
          "789": 2
        }
      }
    }
  }
}

I have use a function like construct IF(condition, trueValue, falseValue) only to explain the intent.

Use case
String based Identify values are quite complex and ability to generate variations based on the value of another dynamic value would make the declarative data model robust.
