This allow to update the running env of kernels.

This will allow resolves some inconsistencies between kernel restart, and actually stopping and starting a kernel session.

In parsley via a few lines in Jupyter Server in update_session, this will let us update the __session__ which is supposed to reflect some information about the current session, and help correct ipython/ipykernel#1102 where renaming a notebook is not reflected in the kernel unless you manually stop/start the session, or restart the server.

This rely on jupyter/jupyter_client#987 and fixes ipython/ipykernel#1102
When a user rename the notebook in the UI, it will update the kernel
env, so that the ``__session__`` variable reflect the new name on the
next restart.

It _does_ seem that each rename of a notebook in JupyterLab creates 4
update_session (2 with name, and 2 with path), but that does not seem to
be a problem in this repository.
