    RANGER-3342 : Need to make the Ranger embedded server work directory 
configurable
    
    Issue:
    Currently the work directory for Ranger embedded server is not 
configurable. Need to make the work directory configurable to a custom location 
so that user can customize if required.
    
    Changes:
    Added configuration to make the work directory configurable for the 
embedded server.
    
    Testing:
    Validated changes locally.
