Add e2e test case for DeleteVolume success on backend volume deletion

Browse Source 
If a backend volume is deleted, DeleteVolume call for the same should
succeed, detecting the image is missing and delete the related OMaps.

This commit adds a test case to ensure this is occuring correctly.

Updates #474
