When using docker in bridge mode, jupyter notebook 5.5 will report

the docker ID as the host name. This will likely confuse users.

jupyter/docker-stacks#642

In future versions of jupyter there will be an option to overide
the hostname. For now fall back to notebook 5.4.

In singularity we continue to use version 5.5
