Title: Allow caller of MultiKernelManager.start_kernel to pass kernel_id.

Sometimes there is a need to create kernel_id's elsewhere in code. This minor change allows a kernel_id to be created outside of the MultiKernelManager and passed in as a kwarg. An exception is raised if the id is already used.
