Context

I am currently deploying Pingvin on kubernetes in high availability (multiple instance of the backend and frontend).

Issue

You are using cache to store OIDC nouce.
You are ussing memory cache.

This work well when you have only one instance of the backend.

But for obvious reason it break when you more that 1 instance.
If the oidc callback arrive to a different backend that pre OIDC request the nonce will not be available and therefore the backend will throw an error because it's nonce is undefined.

PR

This PR introduce the possibility to enable/configure share Redis cache (disable by default).

Note

Thank you for this amazing project ❤️

There will also be an other related PR for PostgreSQL db backend and Kubernetes helm deployment.

Thank you, the implementation looks good to me.

Please also add the configuration variables to the admin settings page.

You have to add the "cache" category to the Sidebar and add the name and description to the translations file.
