title: Add role as CloudFormation template in serverless yml
body: <p>I am trying to invoke a lambda from another, following the example from this answer:</p>
  
  <p><a href="https://stackoverflow.com/questions/35754766/nodejs-invoke-an-aws-lambda-function-from-within-another-lambda-function">Nodejs - Invoke an AWS.Lambda function from within another lambda function</a></p>
  
  <p>The answer says that both lambda functions should have <strong>AWSLambdaExecute</strong> and <strong>AWSLambdaBasicExecutionRole</strong> permissions.</p>
  
  <p>Using Serverless, how can I add these 2 roles to a CloudFormation template in <code>serverless.yml</code>?</p>
