Log message:
	Implement ignore of mda if bit set by skipping r/w of metadata.
	
	We implement ignore of an mda at label_read time by checking for
	the ignore bit, and then skipping the reading of the vgname and
	other information in the metadata.  This will have an effect similar
	to a PV found with no mdas.  Thus, it will look like an orphan in the
	cache until we scan the rest of the system and find a PV with
	metadata, and the mda will not be on the vg->fid->metadata_areas
	list so no read/writes will be done to the metadata area.
