Federated multi-account access for AWS CodeCommit

As a developer working in a large enterprise or for a group that supports multiple products, you may often find yourself accessing Git repositories from different organizations. Currently, to securely access multiple Git repositories in other popular tools, you need SSH keys, GPG keys, a Git credential helper, and a significant amount of setup by the developer hoping to commit to the repository.

Combined with AWS Single Sign-On (AWS SSO) and git-remote-codecommit, you can quickly and easily switch between repositories owned by different groups or even managed in separate AWS accounts.
