Config Settings
---------------
Each service may define a config_settings output variable which returns
Hiera settings to be configured.
Each service may define three ways in which to output variables to configure Hiera
settings on the nodes.
* config_settings: the hiera keys will be pushed on all roles of which the service
is a part of.
* global_config_settings: the hiera keys will be distributed to all roles
* service_config_settings: Takes an extra key to wire in values that are
defined for a service that need to be consumed by some other service.
For example:
service_config_settings:
haproxy:
foo: bar
This will set the hiera key 'foo' on all roles where haproxy is included.
