#1031 Introduce hasSession field in datasource (#1351)

* Introduce hasSession field in datasource That makes isLogged more consistent as it will be '1' only when the player is online. * Fixes * Fix unit testing * Update config doc * Create SessionService * Create test for SessionService, avoid DB operations if sessions are disabled * Cleanup: remove outdated warning for session timeout = 0 - Remove outdated warning - Encapsulate session enabled check in SessionService * Fix failing SessionServiceTest, add data source integration tests for session methods
