Currently the only way to set the git auth is by including it in the context git URL. This can be problematic for certain environments such as ECS where the command args for are stored in logs. Introduces updates to allow setting the authentication info using the environment variables `GIT_USERNAME` and `GIT_PASSWORD`.
