WaitAndCollectErrors waits for all tasks to finish, collects and returns any errors.

type Task 

type Task struct {
	// Name is the name of the task
	Name string
	// Fn is the function which accepts a context and returns an error if there is one.
	// Implementations of Fn should handle context cancellation properly.
	Fn func(ctx context.Context) error
}

Task is a holder for a named function.
