munin plugin varnish_ - feature request: support multiple varnish instances

[Harald Friessnegger]

i forgot to add that the most complicated part in this might be to stay 
backward compatible with existing installations that symlink their plugins 
with just one parameter (the aspect)

varnish_ -> varnish_expunge

instead of the new way (instance + aspect)

varnish_ -> varnish_project1_expunge 



i don't have any idea on how to solve that atm.. :-(
