Ok. So I will keep all authentication parameters in one place: solum.conf

There will be standard section for keystone [keystone_authentication] with
all common parameters like keystone URL, port, etc.

In the default section [DEFAUT] there will be a parameter
Actually it will be a deviation from a common practice as other core
OpenStack components use auth_strategy=noauth (or keystone).
