Move keystone related Locations to VirtualHost section.

Locations /identity and /identity_admin are related to keystone wsgi
and should be inside keystone virtualhost, otherwise they affects another
hosts. For instance, Horizon has /identity location too and it not works in
case when keystone and horizon works under same apache server.
