[aws-appsync] Adding AuthorizationConfig within construction HttpDataSource of the appsync module.

[haruharuharuby]

Adding AuthorizationConfig within construction HttpDataSource of the appsync module.

Use Case

Integrating AWS StepFunctions to the appsync as HTTP Datasource.
Current(24, August 2021) AWS CDK can not configure the authorizationConfig during creating data source.
Currently, That can do only from the AWS-CLI. (create-data-source command)
https://docs.aws.amazon.com/cli/latest/reference/appsync/create-data-source.html

Proposed Solution

I'd like to call the addHttpDataSource method with authorizationConfig object.

    api.addHttpDataSource('ds', endpoint, {
      name: 'custom',
      description: 'custom description',
      authorizationConfig: {
        authorizationType: 'AWS_IAM',
        awsIamConfig: {
          signingRegion: 'us-east-1',
          signingServiceName: 'states'
        }
      }
    });

@BryanPan342 I added PR for this issue. I need to fix some CI checks.

@BryanPan342 is it necessary to add unit test httpConfig that is in CfnTemplate.
It looks like no CfnTest in the UnitTest. I only found the HttpConfig test in integration test.

[BryanPan342]

@haruharuharuby for the unit tests, go to

aws-cdk/packages/@aws-cdk/aws-appsync/test/appsync-http.test.ts

Lines 1 to 20 in 3c116f3

	import '@aws-cdk/assert/jest';
	import * as path from 'path';
	import * as cdk from '@aws-cdk/core';
	import * as appsync from '../lib';
	// GLOBAL GIVEN
	let stack: cdk.Stack;
	let api: appsync.GraphQLApi;
	let endpoint: string;
	beforeEach(() => {
	stack = new cdk.Stack();
	api = new appsync.GraphQLApi(stack, 'baseApi', {
	name: 'api',
	schemaDefinition: appsync.SchemaDefinition.FILE,
	schemaDefinitionFile: path.join(__dirname, 'appsync.test.graphql'),
	});
	endpoint = 'aws.amazon.com';
	});
	describe('Http Data Source configuration', () => {

for some examples!
