adding alb as a gateway type

[jhsinger-klotho]

• Does any part of it require special attention?
• Does it relate to or fix any issue?

closes #109

Adding ALB as a type for expose, which will work with lambda and EKS today (ECS still hardcodes NLBs in the code of the compiler so we need some serious cleanup there.

We add our public subnets to our SG so we can enable the delivery of ALB requests to our backend (These are the private cidr blocks of those subnets)

Because i went down the route of Websocket APIs first i had refactored the APIGateway class to use the LB Plugin in a similar manner. I would have to back out a lot of changes to deploy lib and the index.ts.tmpl file to get the ALB Functionality to work and remove the web socket funcitonality.

The web socket functionality does allow us to create a websocket API GW and a single exec, but isnt too useable outside of that. Cut #117 to dive into that more

Also modularizes all the API Gateway code out of deploylib as a part of these changes.

Standard checks

• Unit tests: Any special considerations? changed the provider unit test, will change some integ tests to
• Docs: Do we need to update any docs, internal or public? https://github.com/klothoplatform/docs/pull/152
• Backwards compatibility: Will this break existing apps? If so, what would be the extra work required to keep them working? yes, this is a new type, i do not believe our IaC should have anything which is not backwards compatible but our logic is very use case based which isnt great (We talked about it in sync and the need to move it to the compiler)

is this old debug?

[jhsinger-klotho]

ah yes, need to remove. I also need to add the topology image i realized.

[jhsinger-klotho]

topology is kind of blocked, i cut klotho #111 so we can discuss and fix it
