Change default of auth_version to v3

Keystone v3 API is CURRENT and the v2 API is deprecated now.
So we need to change the default config of auth_version to fit for
current API status.

NOTE: Devstack changes this config to "v2" when enabling the v2 API.
      So we will still test the v2 API on the gate until we will
      change Devstack (I801e6740258ddea2a1b628a209970e0307d39d12)
