Smaller Fixes

• Support for shelling out to authenticate, needed for better GCP integration.
• Both IAM role and K8s service account can be simultaneously used now.
• Labels and annotations specifiable on Launch Plan creation
• Serialization of elements no longer uses the older SdkTask/Workflow/LaunchPlan classes.
• Added a Dockerfile for flytekit itself, publishing a Debian buster image.
