Describe the bug

When a node leaves gracefully, there is warning:

> [Context=offlineSessions] ISPN000312: Lost data because of graceful leaver

Version

26.2.x, main

Regression

[ ] The issue is a regression

Expected behavior

There shouldn't be a warning as this is expected as user and client sessions have only a single owner.

Actual behavior

There is a warning message that might make admins uneasy. See https://github.com/keycloak/keycloak/issues/39544#issuecomment-2890066506

How to Reproduce?

Run a rolling restart of the pods.

Anything else?

We might add a log filter for that similar to https://github.com/keycloak/keycloak/blob/9c65d27d5b746c9de949faccce67c5597817b0fc/quarkus/runtime/src/main/java/org/keycloak/quarkus/runtime/logging/KeycloakLogFilter.java#L37
