Notify listeners when a host has been added to a cluster, is about to be removed from a cluster, or has been removed from a cluster
This PR addresses the following JIRA ticket:
https://issues.apache.org/jira/browse/CLOUDSTACK-8813
The problem is that there needs to be notifications sent when a host is added to, about to be removed from, and removed from a cluster.
Such notifications can be used for many purposes. For example, it can allow storage plug-ins to update ACLs on their storage systems. Also, it can allow us to clean up IQNs from ESXi hosts that are no longer needed.
