Performance: Find commands: do not process members by default
    
    In all *-find commands, member attributes shouldn't be processed due
    high amount fo ldpaserches cause serious performance issues. For this
    reason --no-members option is set by default in CLI and API.
    
    To get members in *-find command option --all in CLI is rquired or
    'no_members=False' or 'all=True' must be set in API call.
    
    For other commands processing of members stays unchanged. WebUI is not
    affected by this change.
