A utility docker image to try out the AWS Cloud Development Kit

See https://github.com/awslabs/aws-cdk

To try it out:

• Make sure you have AWS CLI credentials configured in ~/.aws

• Run make shell to get a shell running in a cdk-utils container

• Run AWS CLI commands e.g. aws s3 ls

• Try the CDK example app e.g.

  mkdir app
  cd app
  cdk init --language=typescript
  npm run build
  cdk synth
  cdk deploy

  You should see a CloudFormation stack created in your account with a single resource of type AWS::CDK::Metadata.
