zpool/zfs: Add '-a|--all' option to scrub, trim, initialize

Add support for the '-a | --all' option to perform trim,
scrub, and initialize operations on all pools.
Previously, specifying a pool name was mandatory for
these operations. With this enhancement, users can now
execute these operations across all pools at once,
without needing to manually iterate over each pool
from the command line.

+# DESCRIPTION:
+#	Verify 'zpool trim -a' works correctly with multiple pools
+#
+# STRATEGY:
+#	1. Create multiple pools.
+#	2. Start a trim on all pools using 'zpool trim -a'.
+#	3. Verify that the trim is started on all pools.
+#	4. Wait for the trim to complete.
+#	5. Verify that the trim is complete on all pools.
+#	6. Start a trim on all pools using 'zpool trim -w -a'.
+#	7. Verify that the trim is complete on all pools.
+#	8. Now test the -c and -s options on multiple pools with -a.
+#	9. Verify that the trim status is correct for each option.
