Directory creation changes

 - create a repair_permissions.sh to set file/dir ownership to the
   expected values
 - remove permission setting from create_zfs_datasets.sh, have it chain
   to repair_permissions.sh
 - create a script to create directories on a non-zfs setup
 - create datasets for hivesense/ollama, support new hivesense options
   for downloading matrixes (requires hivesense!40 )
