Add a server to ganglia monitoring

Gmond (Deamon Ganglia Monitoring): This service will retrieve some information about the node to be monitored.

Gmetad (Ganglia Meta Daemon): Gmetad will collect data from all gmonds. Including gmond which is installed on the client. Gmetad only needs to be installed on the server side only.

RRD (Round Robin Database): Used to store data on ganglia.

Ganglia Web: A web interface for displaying data graph displays and matrices from rrd tools.
