Describe the bug

When Keycloak performs the Liquibase upgrade, it misses to clear a thread local context, so the session is never garbage collected.

As this is an effort to find all those places, this is a housekeeping task. It will reduce the memory usage of Keycloak slightly in this place, and to a larger extent in other places.

Version

main

Regression

Expected behavior

Thread locals should be removed when no longer used.

How to Reproduce?

Start up Keycloak, create a memory dump, and search for QuarkusKeycloakSession

Anything else?

I'll create a PR.
