[hobbit] grouping methods

[Hubbard, Greg L]

I have used this method with great success, but it is a pain in the
you-know-what to maintain.  It would be nice if this "router" tagging
could be made recursive so you only have to specify one upstream host
for each host, assuming that the upstream host is also in Hobbit.  As it
is today you have to specify the full path to each "leaf" and this can
get long.

If this is a situation of routed networks, Hobbit can know about that
with directives in the bb-hosts file.  If it knows a host behind a
router is down, it will only notify for the router, not the hosts behind
the router.
