It is noted that the keystoneclient might go away and hence we should avoid using it. We will make use of the recommended 'keystoneauth1.session' instead. This Patch Set is meant to do the following 1) Add service_session(common function) to retrieve keystone session 2) Add service_endpoint to retrieve keystone endpoint for the requested service type 3) Update service_token to avoid the usage of keystoneclient Change-Id: I69dee3360365a1138bb7482add5e1477b4360111
