Image Creation Logic not aligned with Openstack Operation

[Dishant]

Following are the corresponding operation mapping for image creation in context with AWS and Openstack

- Image Creation in AWS <> Creating Snapshot from Running Instance Openstack

- Register Image in AWS <> Adding Image in Openstack.

In AWS Image Creation will create an AMI from the existing instance and store it under images.
Wherein the same operation when done through Openstack EC2API is creating a volume snapshot.

To Verify the operation ec2api is running the describe-images operation, which is trying to read the images from openstack. But as the image creation creates a snapshot, it won't be able to validate the operation and will get stuck at pending state.
