create an interface that uses AWS Cloudformation to mutate resources and add headers to the HTTP requests that the AWS SDK makes

Script
const { CloudFormation } = require('@aws-cdk/aws-cloudformation');
const { HeaderRequestOptions } = require('aws-sdk/lib/request');

const cloudformation = new CloudFormation();

const options = {
    requestOptions: {
        customUserAgent: 'my-custom-user-agent',
        customRequestHeaders: {
            'X-Test-Header': 'Test-Value'
        },
        applyChecksum: true
    }
}

cloudformation.createStack(options);
