Feature/page template

[raethlein]

Add tabs for "Change Password" and "Authorize Users" into the page by using JupyterHub's template extension functionality (see documentation):

To use it, the user has to add the templates folder to the templates path in the JupyterHub configuration file. Example:
c.JupyterHub.template_paths = ["/usr/local/lib/python3.5/dist-packages/nativeauthenticator/templates/"]

To use it, the user has to add the templates folder to the templates path in the JupyterHub configuration file. Example:
c.JupyterHub.template_paths = ["/usr/local/lib/python3.5/dist-packages/nativeauthenticator/templates/"]

The template path depends on python version and method used to install the nativeauthenticator package, perhaps there is some way we could automate the template inclusion? (I think this needs some change upstream)

Otherwise, thanks for this, it is a nice addition to nativeauthenticator.

[raethlein]

Good point! It would be possible to make it independent of the underlying folder structure like this:

import os, nativeauthenticator
c.JupyterHub.template_paths = ["{}/templates/".format(os.path.dirname(nativeauthenticator.__file__))]

This could be added to the documentation as an optional feature, but I understand if a completely automated solution would be preferred.

Hi @raethlein ! Thank you for your contribution! I tried both things locally and couldn't make it work. Any idea what I may be doing wrong?

[chicocvenancio]

@leportella I had it working with c.JupyterHub.template_paths = ["/home/jovyan/.local/lib/python3.6/site-packages/nativeauthenticator/templates/"] on a jupyterhub/k8s-hub:0.9-dcde99a image with nativeauthenticator and this PR installed. (functionally the same as the last suggestion by @raethlein)

[leportella]

Yeah, this is definitely not ideal. I was wondering if we could automatically load this from inside the code. @yuvipanda do you have any thoughts on this?

[lambdaTotoro]

This PR hasn't seen any activity in a while, but I still think it would be lovely to have.
I tested @raethlein's last suggestion locally and it worked immediately. And I don't think the extra step in the configuration is too much to ask.

[lambdaTotoro]

I decided to merge this PR for the reasons above. I've tested it again today and like I said before, @raethlein's code to automatically find the template files works flawlessly. I have added it to the documentation as well.

[consideRatio]

@lambdaTotoro when you mention @raethlein's code to automatically find the templates files, are you referring to this?

import os, nativeauthenticator
c.JupyterHub.template_paths = ["{}/templates/".format(os.path.dirname(nativeauthenticator.__file__))]

[lambdaTotoro]

That's the one, yes. Should be identical to the one in the docs.
