      Background: the setdirstripe LMV for remote directories and the LMV for DAOS foreign layouts represent similar directory layouts but differ in content: in the DAOS case, it describes a "directory tree" stored externally to Lustre. The existing enable_remote_dir_gid parameter controls which group can explicitly create subdirectories on MDTs other than the parent's (e.g., root only, a designated admin/power user group, or any user). 

      The proposed change will introduce a new tunable "enable_foreign_dir" which will will separate control of foreign directories from enable_remote_* control.

      This will allow the governing of foreign creation on remote DAOS "directories" and by whom.
