feat: pass DataFetcherEnvironment to arguments

[smyrick]

Clients can now specify DataFetchingEnvironment as one of their arguments. It will not be generated as part of the schema but will be passed down on execution and gives access to all the context of the query, parent fields and their arguments, and anything else that is on the graphql.schema.DataFetchingEnvironment

This is the example query I have added

@Component
class EnvironmentQuery : Query {
    fun nestedEnvironment(value: Int) = NestedNode(value)
}

data class NestedNode(
    val value: Int,
    val parentValue: Int? = null
) {
    fun nested(environment: DataFetchingEnvironment, value: Int): NestedNode {
        val parentValue: Int? = if (environment.executionStepInfo.hasParent()) environment.executionStepInfo.parent.getArgument("value") else null

        return NestedNode(value, parentValue)
    }
