Implement OIDC as an alternative to LDAP

[dimitrihof]

Is your feature request related to a problem? Please describe.
Would like to use PILOS, but we are only working with SAML and OIDC. So seeing one of those implemented would be great, preferable OIDC as it is the state of the art.

Describe the solution you'd like
Implement full oidc (sso/slo etc.)

@dmtrhfr We currently plan to implement Shibboleth, would this work for you?

[dimitrihof]

As far as I understand shibboleth is saml compatible, so it probably should work as well.
Maybe if our organisation decides to use PILOS, we could implement OIDC too.

@dmtrhfr Do you have a SAML dev. env. setup that I can use, e.g. docker compose and some config files for keycloak or something similar?
