Prepare AWS Governance environment + Migration of Github runner and ECR to it

[tltran-legion]

Summary

We need a centralized account for shared services like build services, monitoring services, legionlabs AMI, Container Images Registry.

Current State

Currently, we are using legionlabs-playground's account to host services such as build machines, AMI, Container Images, engine services. legionlabs-playground, should only be use for exploration and experimentation purpose. It should not host services and data that are stable and that will be used by other accounts.
