Excluding hosts from hostgroups?

Hm.  My mind rebels against this notion because it doesn't really make
sense.  Either a hostgroup has a host or it doesn't.  There is no half way.

BUT, I could see being useful on a service:

service ssh {
	hostgroup			webservers
	exclude_hosts		nossh-1,nossh-2

	-or-

service ping {
	host				*
	exclude_hosts		noping-1,noping-2
