Add script to test jack_property (Metadata)

Running script 'jack_property_test.sh' with recent jack1 and jack2 git builds show different results.
Notes:
	-jack1 gives only false positives due to a small text change
	-jack2 has issues using client name as subject/identifier/uuid
		-> see '**      FAILED' lines
	-jack1 is much faster in performing the same script
	-running the script in a loop causes memory problems with jack2
