issue603: fix monit config madness

added new node['nova']['platform']['nova_*_procmatch'] regular
expressions for daemons.  replaces old *_process_name attribute, where
applicable (not all process names were extracted into attributes--many
were hard-coded into openstack-monitoring recipes).

clean up and organize all the platform attributes
(found some extra bugs by doing this).
