adding Flask-OIDC in requirements.txt

[cleman95]

Helllo,

I'm using superset on my kubernetes cluster. I deployed it with the helm chart from stable/superset. While playing with superset I was trying to use keycloak as an authentication system for superset. So i add to put some extra config files in the helm chart but nothing too difficult. The problem is that i needed to have Flask-OIDC installed. So I had to rebuild your image to do so.

I thinks that it could be great to have this library directly in your image since it is the only way to use something like keycloak with superset. Would you mind adding it in the requirements.txt ?

The version I used is Flask-OIDC==1.4.0 . Here is a link to the library

Sounds great—can you open a PR?
