Seamless GitOps

## Feature Description
Keep Hasura cloud projects synchronized with git commit. Plug and play with the git tool of your choice and achieve any CI/CD workflow with Hasura

## User value / outcome
Improves the current CI/CD deployment with easy rollback, rollforward and deploy loops. CI/CD (local development, testing) and version management is now straightforward and easy to onboard.

## Current status (design, alpha, beta etc.)
Currently in design phase. Expected to come out in phases starting from June 2023 as part of the Beta launch

Start with the feature description and its stated design-phase status, then review the planned phased rollout for the Beta launch. Define what GitOps synchronization for Hasura Cloud projects must support, including a user-selected git tool, CI/CD workflows, rollback, rollforward, and deployment loops; done should be an agreed implementation scope rather than an isolated edit.
