Add jupyter-delete-all-kernels

Browse source 
Add this to `kill-emacs-hook` to ensure that connection files are cleaned up in
a more reliable fashion. The connection files are cleaned up when the kernel
process is garbage collected, but this won't happen when killing Emacs.

* jupyter-kernel-manager.el (jupyter-delete-all-kernels): Do it.
Add to `kill-emacs-hook`.
