Users can now provide their own scripts to be run with 'zpool iostat/status -c'. User scripts should be placed in ~/.zpool.d to be included in zpool's default search path. Provide a script which can be used with 'zpool iostat|status -c' that will return the type of device (hdd, sdd, file). Provide a script to get various values from smartctl when using 'zpool iostat/status -c'. Allow users to define the ZPOOL_SCRIPTS_PATH environment variable which can be used to override the default 'zpool iostat/status -c' search path. Allow the ZPOOL_SCRIPTS_ENABLED environment variable to enable or disable 'zpool status/iostat -c' functionality. Use the new smart script to provide the serial command. Install /etc/sudoers.d/zfs file which contains the sudoer rule for smartctl as a sample. Allow 'zpool iostat/status -c' tests to run in tree.
