publish / deployer - Add new type for lambda-dispatch

[huntharo]

Motivations

• We need to know if an app version is pointed at a lambda-dispatch router
• We need the Lambda ARN for that version / alias so we can add it to the request header for the lambda-dispatch router to use
• We need a type to guide the Lambda@Edge routing logic for these
• We may want to set a default lambda-dispatch router endpoint for the deployer so that each invocation of the CLI does not have to specify the lambda-dispatch router endpoint

Acceptance Criteria

• Add CLI app type
• Add new app type to DB schema module
• Add new app type to Deployer Service
• Add new app type to example Lambda@Edge routing code
