Ensure LBaaSLoadBalancer object is created for lb clean up

When cleaning up the leftover lbs the LoadBalancer
openstacksdk object is being used, instead of retriving
it's fields and populating the LBaaSLoadBalancer object,
resulting in a mapping issue. This commit fix the issue
by populating LBaaSLoadBalancer object with the needed fields.
