server-addons: fix for hostgroup issue in brick status event handler
Macro "$HOSTGROUPNAME$" is used in brick status event handler. But this macro gives only one of the host group to which the host belongs to. But in gluster monitoring, all gluster hosts will have two host groups ('gluster-host' and a host group with cluster name). So using the macro "$HOSTGROUPNAMES$" to pass all the host groups to event handler and internally getting the currect cluster name.
