DeployBlueGreenAction class to handle CodeDeploy deployments

[joaoricardo000]

• Add a new option for ecs deploy function.
• Code Deploy Application Name --cd-application-name AppECS-service-name
• If --cd-application-name is given, a DeployBlueGreenAction instance is created to handle the creation and monitoring of the CodeDeploy deployment process.

Example call/output:

$ ecs deploy cluster-name service-name --task task-def-name --image docker_image --cd-application-name AppECS-cd-service-name

Anything I can do to get this over the finish line? or, another option would be to have a flag to disable the deploy after updating the task def.
