[MRG] Update server proxy and rsession proxy

[betatim]

Both haven't been updated in a long time (~1yr) so we should refresh
them. This brings both to the latest commit in their repos.

Can anyone remember if there were big changes in either that would break things for users of repo2docker?

I've not followed the changes for that long, I'm not sure, but I know there is no changelog available. But, thanks to @choldgraf's github-activity project, I present the results below from running:

github-activity --kind=pr -o prs.md jupyterhub/jupyter-server-proxy --since 7ac0125

@consideRatio can you make a new release and add 1.3.2 to https://github.com/jupyterhub/jupyter-server-proxy/releases? The reason I updated server proxy was to see if the increased timeout deals with jupyterhub/jupyter-server-proxy#146. It seems it does. At least I don't get an error locally any more. The timeout change hasn't been released yet though. (I am perfectly fine using a particular commit instead of a release though, so only make a new release if you have time.)

@betatim ok!

@ryanlovett @yuvipanda I'm making a new release of jupyter-server-proxy containing a single PR (jupyterhub/jupyter-server-proxy#183) that I consider a bugfix, so from 1.3.1 to 1.3.2. Guided by the principle in release.rst saying:

We should release early & often, following semver wherever possible.

UPDATE: Done, see https://pypi.org/project/jupyter-server-proxy/
