By replacing grpc with ttrpc, we can reduce total memory runtime requirements and binary size. With minimal code changes, the shim can now be controlled by the much lightweight protocol, reducing the total memory required per container. When reviewing this change, take particular notice of the generated shim code. Signed-off-by: Stephen J Day <stephen.day@docker.com>
