This adds support for arbitrary object definitions via the conf
key in the Nagios chart. This allows for customizing the
definitions required by different deployment targets instead of
assuming all nagios deployments are monitoring and targeting the
same hosts and executing the same service checks and commands.
This also adds reference overrides to the chart for elasticsearch,
postgresql, and openstack nagios objects that are deployed in the
single and multinode jobs here
