automatically detect which hosts Nagios knows about

[dpocock]

Currently, ganglia-nagios-bridge sends checkresults to Nagios for all hosts it discovers in the gmetad XML

If the Nagios server doesn't have a static configuration for some of those hosts or metrics, it wastes CPU cycles processing that content from the checkresults file and it also logs a lot of spurious warnings about those entries.

It would be useful for ganglia-nagios-bridge to find out which hosts and services Nagios really knows and only write checkresults for those hosts
