Ganesha config options not being registered

[Ramana Raja]

For instances of classes that inherit both GaneshaMixin and ShareDriver classes (e.g. GPFSShareDriver) currently don't seem to have the ganesha specific configuration options. This is because the initialization method of the ShareDriver class incorrectly calls the init_execute_mixin() method of the ExecuteMixin class instead of the init_ganesha_mixin() method of the GaneshaMixin class that helps register the ganesha configuration options. Please see the incorrect call here,

    driver: Fix ganesha config option registry

    To register the ganesha config options, the initialization method of
    the ShareDriver class incorrectly calls the ExecuteMixin class's
    init_execute_mixin() method. Instead call GaneshaMixin's
    init_ganesha_mixin() method.
