Modified files:
	test/shell     : lvcreate-thin.sh 

Log message:
	Update thin test for thin_check
	
	Test if thin_check is present in system and disable its use, when its missing.
	
	Add testing for poolmetadatasize.
	
	FIXME: Allocation policy for metadata pool might need some relaxing.
	(For now it needs to put all block on one PV.)
