 * Returns the actual cookie name for the specified neutral name such as "P", "C" etc. 
 * To help separate cookies between different running musubi environments such as
 * production, trunk, staging etc, the actual cookie names are the nuetral name concatenated with 
 * a suffix. This helps to prevent them from overlapping with cookies from different 
 * environment of musubi.
 * For example for STAGING environment given the name "P" => will return "P_staging".
 * 
 * The result cookie name is the concatenation of the 'name' + '_' and the 
 * configured cookies name suffix for the current running environment / run mode.
