Load resource configName.properties first. Then load configName-deploymentEnvironment.properties
into the system wide configuration. For example, if configName is "application", and deployment environment
is "test", this API will first load "application.properties", then load "application-test.properties" to
override any property that also exist in "application.properties".

@param configName prefix of the properties file name.
