Disable the cherrypy dispatch method translation for dot and hyphen
    
    This will prevent cherrypy from automatically translating dots and hyphens to underscores.
    This is useful so we can support client IDs and service provider names with dots or hyphens
    in them while still keeping them uniquely identifiable.
