Implement the resize function for RAID0. raid0_resize() calculate the new raid_bdev's block count and if it is different from the old block count, call spdk_bdev_notify_blockcnt_change() with the new block count. A raid0 bdev always opens all base bdevs. Hence, if the size of base bdevs are reduced, resize fails now. This limitation will be removed later. Add a simple functional test for this feature. The test is to create a raid0 bdev with two null bdevs, resize one null bdev, check if the raid0 bdev is not resize, resize another null bdev, check if the raid0 bdev is resized. test/iscsi_tgt/resize/resize.sh was used a reference to write the test. Using jq rather than grep&sed is better and hence replace grep&sed by jq of test/iscsi_tgt/resize/resize.sh together in this patch.
