Service discovery and CodeDeploy support

[snarkyboojum]

These seems to be the two biggest gaps currently.

I could build a couple of custom resources and then bundle those as CDK constructs. Should make it clean-ish in terms of composition, and then we could use those constructs to plug the gaps in the current script.

Thoughts?

Actually, we can just use the AWS CloudFormation library for CodeDeploy & Service Discovery:

See,
https://awslabs.github.io/aws-cdk/versions/0.8.1/cloudformation.html
https://awslabs.github.io/aws-cdk/versions/0.8.1/refs/_aws-cdk_aws-codedeploy.html
https://awslabs.github.io/aws-cdk/versions/0.8.1/refs/_aws-cdk_aws-servicediscovery.html

Would still be neat to wrap these up as constructs, but should be easy enough to write it all inline in your current script.

Service discover for MySQL is implemented (with a workaround given it’s not supported as park of ECS service yet) - this is used to resolve MySQL from Wordpress container.
See: aws/aws-cdk#1554

I didn’t add code deploy as there is no way to tie it up with ECS service until that feature is made available through CFN or we create a custom resource to build that service.
