Fix elasticsearch test configuration and others fixes/improvements

[mshima]

• configure non reactive elastic search to use RefreshPolicy.IMMEDIATE, reactive already uses it.
• move elasticsearch cleanup to a dedicated AfterEach block and verify the cleanup
• add xpack.security.enabled=false setting to elasticsearch testcontainer which is already set at docker compose file (stops generating tons of warnings)
• when implementing Persistable interface, new field should be ignored by Jackson.
• add log safe marker to an initialization log.
• add docker-compose npm script for Microservices+workspaces.
