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.

> This has probably always been an issue in CloudStack, but only recently have
> I been getting requests to implement this. Also, it has only been noticeable
> since storage plug-in support was added to CloudStack in 4.2.
> If you have a custom storage plug-in that makes use of access control lists,
> your plug-in needs to be notified when a host is added to or removed from a
> cluster (so that you can update your ACL).
> Also, these kinds of events are your opportunity to tell the newly added (or
> removed) host to update its knowledge of, say, IQNs.
