  - Refactoring Resource Resolution Component

    Use Case:
    ----------
    Input Value (IV): It can be API Input Value or API Default value

    If a Resource is marked as Input
        -> pick IV

    If a Resource is marked as other than Input
        -> pick IV
        -> if IV is not present then resolve it as per DataDictionary Definition

    ** Return Error if Resource is not resolved using assert : ResourceAssignmentUtils.assertTemplateKeyValueNotNull
