No need to discover auth uri on guess vm

[Perry]

Looking at project os-collect-config, it changed auth_url to one with no version and then discover auth_url again. Actually there is no any benefit but some problem. First of all, the call to keystone with Discover takes time; Secondly, the Discover always return internal url of keystone - that cause when a public url is needed.

    def __init__(self, auth_url, user_id, password, project_id,
                 keystoneclient=None):
            ...
            auth_url_noneversion = auth_url.replace('/v2.0', '/')
            discover = ks_discover.Discover(auth_url=auth_url_noneversion)
            v3_auth_url = discover.url_for('3.0')
            ....

The exact code place is os-collect-config/keystone.py

I marked this defect as invalid as I realized that the keystone.py replies on keystone discovery to get admin url of keystone. Removing usage of discovery has impact to many unit testing cases.

Instead I will seek for a workaround on my side to workaround the problem.
