    Set empty openstack_release option

    globals.yml have the highest var precedence in Ansible vars
    as is added in kolla-ansible as -e @globals.yml
    Setting openstack_release: "auto" causes error while
    deploying/pulling as this var override the fact set in site.yml.

    Value in globals.yml should be a real kolla version
    (3.0.0, 4.0.0, etc)
    Value in group_vars/all works fine with auto.
