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.
