Fix for Issue #20

[ksatchit]

Code Changes :

• The setup-test-images role creates separate tar file for each test image suffixed with image version
• The load-test-images role loads the images from above individual tarfiles
• Changes in logic to detect presence of image tar files in "files" folder of load-test-images role
• Reverts an additional global variable introduced in Placeholder for roles & playbooks to address OpenEBS issue #463 #19

Fixes #20
