commit f77e72a97118570558d9a9c6c244a9ae117d419a
Author: Kai Wang <[email protected]>
AuthorDate: Thu Jun 16 18:15:34 2022 +0800

    Add config of nar extraction directory for the broker (#15778)
    
    ### Motivation
    
    Currently, some users want to change `narExtractionDirectory` config, but 
users may be confused, because the `broker.conf` and `standalone.conf` config 
files don't Include `narExtractionDirectory` config.
    
    ### Modifications
    
    Add config of NAR extraction directory for the broker configuration
