#1 Filter hosts/services by hostgroup(s) / servicegroup(s)

[Stig H. Jacobsen]

Just like --hosts:

--hostgroups=servers,netgear
--servicegroups=mail,web

Possibly also .conf settings for this (and --hosts).

Hostgroups and servicegroups are not in the status.log,
so nsc will have to read the nagios.cfg file, look for
cfg_file= statements and parse those to get to know
about the groups.
