This is a continuation for my previous pull request:1199, in this request, I modified all other keystone services (earlier I modified only IdentityService, now I modified ProjectService, RoleService,..).
@vinodborole Kindly review.

I am trying to upload large image data(~2gb) to glance using openstack4j glance v2 APIs, but it's giving me OutOfMemory error. I have gone through the issue: #525
but nothing seems to fix this issue.
Below is the code I'm using:
Image image = os.imagesV2().create(Builders.image().name(imageName+"_testAPP").build());
final Payload payload = Payloads.create(new File(imagePath + "/" + imageName));
image =image.toBuilder().containerFormat(ContainerFormat.BARE).diskFormat(DiskFormat.QCOW2).build();
ActionResponse response = os.imagesV2().upload(image.getId(), payload, image);

The last line gives OutOfMemory error as the image file size is ~2gb.
Please let me know how to get this to work.
