refactor(aws-codepipeline): Re-structure the CodePipeline API.

1. [BREAKING] Introduce a new aws-codepipeline-api package, and move the Actions API there.
2. [BREAKING] Move the service-specific Actions back into their service packages.

 ## CDK Constructs for AWS CloudFormation
+
 This module is part of the [AWS Cloud Development Kit](https://github.com/awslabs/aws-cdk) project.
 
+### CodePipeline Actions for CloudFormation
+
+This module contains Actions that allows you to deploy to CloudFormation from AWS CodePipeline.
+
+For example, the following code fragment defines a pipeline that automatically deploys a CloudFormation template
+directly from a CodeCommit repository, with a manual approval step in between to confirm the changes:
+
+[example Pipeline to deploy CloudFormation](../aws-codepipeline/test/integ.cfn-template-from-repo.lit.ts)
+
+See [the AWS documentation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/continuous-delivery-codepipeline.html)
+for more details about using CloudFormation in CodePipeline.
+
+#### Actions defined by this package
+
+This package defines the following actions:
+
+* **CreateUpdateStack** - Deploy a CloudFormation template directly from the pipeline. The indicated stack is created,
+ or updated if it already exists. If the stack is in a failure state, deployment will fail (unless `replaceOnFailure`
+ is set to `true`, in which case it will be destroyed and recreated).
+* **DeleteStackOnly** - Delete the stack with the given name.
+* **CreateReplaceChangeSet** - Prepare a change set to be applied later. You will typically use change sets if you want
+ to manually verify the changes that are being staged, or if you want to separate the people (or system) preparing the
+ changes from the people (or system) applying the changes.
+* **ExecuteChangeSet** - Execute a change set prepared previously.
+
