I am trying to register an external cloud through ESR.

But the flavor and other information's of the cloud are not stored in AAI database.

I debugged the Multicloud-windriver pod logs, and found there is a problem in forming the url to get the cloud informations  from openstack.

when I tried to manually append the https endpoint with v3 in the registration.py, it worked out, but not the same with v2.0.
