Nagios: Reduce Nagios concurrent checks and workers

Browse Source 
This reduces the maximum concurrent checks Nagios will execute to
prevent process sprawl on the host. This also reduces the number
of default workers to a single worker, to prevent Nagios from
forking off multiple processes that then execute service checks
and commands in parallel
