KIE server will not always deploy services, stay in sync with Business Central when Business Central is deployed HA on-premises

To sync with Business Central (BC) and deploy services when the user deploys them through UI, KIE server initiates a connection to Controller, which is a component of BC.

In an HA deployment, Controller instances are not synchronized. And load-balancing means that a KIE server can be connected to any of the cluster instances randomly. If a user uses the UI to deploy a service on the KIE server, but the user is connected to another cluster instance, the service is never deployed. Other sync issues are also possible.

[NOTE ENG]
This requires in case of using VFS to sync / share the state.

<property name="org.uberfire.nio.git.dir" value="/opt/kie/niogit"/>
Kie Server will notify the controller about needs to be refreshed and it will pick it up from there.

In case of openshift strategy we should be fine.

[ENG NOTE]
Added a property to disable notification from kie server to controller. By default is true

org.kie.server.update.notifications.rest.enabled=true
