Complete switch from glanceclient to SDK for image service

In https://review.opendev.org/#/c/650374/ a work has been started to
switch image service support from glanceclient with all it's
dependencies to the SDK version. With this change version 1 (anyway
deprecated since ages) is also being switched to SDK.
