Nagios acknowledgement (with check_logfiles plugin)

[Kyle O'Donnell]

We configure check logfiles as a volatile service and choose not to
use the sticky option.  Some logs we configure check-logfiles to send
a message via nsca for each pattern match, ensuring we don't miss any
notifications.  We also configure check-logfiles services not to send
out recovery messages, and only schedule downtime or disable
notifications during maintenance.
