Subject: [PATCH] Add zconfig.sg test script.

This is an initial script for validation of zfs/zpool configuration.
For now there is only one test here to ensure that /etc/zfs/zpool.cache
is being updated properly from the kernel module.  Additional tests
should be added, I believe Richardo said there was an existing test
suite out there which validated the behavior of many zpool/zfs commands.
It would be nice to add that as appropriate.
