### Problem to solve
<!-- What problem do we solve? -->
It's hard to get started with deploying an application. Auto DevOps is a great start and shows a complete CI/CD pipeline for many applications, but has several limitations:
1. Auto DevOps only deploys to Kubernetes
1. The pieces aren't easily reusable outside Auto DevOps.
1. There's no help for deploying in other ways, other than documentation.
### Intended users

### Proposal
<!-- How are we going to solve the problem? Try to include the user journey! https://about.gitlab.com/handbook/journeys/#user-journey -->
1. Start with composable Auto DevOps.
1. Generalize the deploy piece in a way such that anyone can swap in their own way of deploying.
1. Provide pre-packaged includes so that common deploy targets are covered. Want to deploy to an AWS VM instead? Include the `aws-vm` template. Want a custom deploy target? Start from one of the templates and write what you need.
1. Then let people publish their includes so they can be re-used by your organization, or by the broader community.
1. Make it easy for people to discover appropriate templates from GitLab.com, the web IDE, VS Code, etc.
1. To make templates more flexible, allow declaring required and optional parameters to be consumed by the template, and surface those parameters in the template picker UI.
1. What else?
Do this in such a way that a single CI/CD pipeline could leverage multiple deploy targets. e.g. staging might be to Heroku, but production is an AWS VM.
Ideally, provide a best practice of testing these templates so they're less brittle and don't lead to plugin hell.
### Permissions and Security
<!-- What permissions are required to perform the described actions? Are they consistent with the existing permissions as documented for users, groups, and projects as appropriate? Is the proposed behavior consistent between the UI, API, and other access methods (e.g. email replies)?-->
### Documentation
<!-- See the Feature Change Documentation Workflow https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html
Add all known Documentation Requirements here, per https://docs.gitlab.com/ee/development/documentation/feature-change-workflow.html#documentation-requirements
If this feature requires changing permissions, this document https://docs.gitlab.com/ee/user/permissions.html must be updated accordingly. -->
### Availability & Testing
<!-- This section needs to be retained and filled in during the workflow planning breakdown phase of this feature proposal, if not earlier.
What risks does this change pose to our availability? How might it affect the quality of the product? What additional test coverage or changes to tests will be needed? Will it require cross-browser testing?
Please list the test areas (unit, integration and end-to-end) that needs to be added or updated to ensure that this feature will work as intended. Please use the list below as guidance.
* Unit test changes
* Integration test changes
* End-to-end test change

### What does success look like, and how can we measure that?
<!-- Define both the success metrics and acceptance criteria. Note that success metrics indicate the desired business outcomes, while acceptance criteria indicate when the solution is working correctly. If there is no way to measure success, link to an issue that will implement a way to measure this. -->
### What is the type of buyer?
<!-- Which leads to: in which enterprise tier should this feature go? See https://about.gitlab.com/handbook/product/pricing/#four-tiers -->
