The zimport.sh script makes use of the zpool-create.sh script to construct test pools for importing with older versions of ZoL. It is desirable to have a way to disable all the features so new pools can be imported with older code. The simplest and most flexible way to achieve this was to merge the VERBOSE_FLAG and FORCE_FLAG in to a single ZPOOL_FLAGS variable. The contents of this variable will be used in the 'zpool create' allowing us to easily pass arbitrary flags.
