示例1: RegisterTaskDefinitionIfNeeded
// RegisterTaskDefinitionIfNeeded checks if a task definition has already been
// registered via the provided cache, and if so returns it.
// Otherwise, it registers a new one.
//
// This exists to avoid an explosion of task definitions for automatically
// registered inputs.

request *ecs.RegisterTaskDefinitionInput,
taskDefinitionCache cache.Cache) (*ecs.TaskDefinition, error) {

// register the task definition and create a cache entry
