Graph QLScalar
data class GraphQLScalar(val scalar: String, val type: String, val converter: String) : Serializable
Holds mapping between custom GraphQL scalar type, corresponding Kotlin type and the converter that will be used to convert to/from raw JSON and Java type.
In order to limit the amount of plugin dependencies, we cannot use client-generator GraphQLScalar directly as it is declared as a compileOnly dependency (which will be available on the worker classpath only). We need to re-define the same object here so it will be accessible from build file configurations.
