Deployer - Delete in Parent Account Fails

[huntharo]

Motivations

• Deleting apps from child accounts fails
• The child account deployer proxies the delete to the parent account
• The parent account tries to GetAlias on the Lambda, which doesn't exist in the parent account

To-Do

• Split Delete into Child Account portion and Parent Account portion
• Child Account should cleanup the Alias
• Parent Account should remove from DB, cleanup API Gateway, and cleanup S3
• Can be handled with a simple boolean flag in the request
• Add test during pipeline of delete of app version from child account

because no resource-based policy allows the lambda:GetAlias action
