Task: Evaluate to make direct login possible after login into UT/Geonode and opening the other Application

Task Description

So called "single sign on" behaviour is expected.
Hence, a user being logged in to the upload tool should be able to switch to geonode and is logged in using the already present cookies/tokens of keycloak/ORCID.
