Description:
It was found that uploading docker images inside a nested path caused failure in attaching build properties in the artifacts due to invalid path construction:
eg: docker-repo/myorg/image:latest when uploaded, cli tried to attach properties on docker-repo/image:latest, as a result attaching properties caused 404 not found failure.

Solution:
instead of using image full name which returned image:latest, we are using image full name without repo which returns myorg/image:latest
