Comment 10 for bug 1543102

Verified on MOS 7.0 + MU6 updates.

Checked scenarios of creation networks and images with "Тест1" name(creation of instances works correctly, nova is not affected):

Before we can't check network list(or image list):
root@node-4:~# neutron net-list
'ascii' codec can't encode characters in position 586-591: ordinal not in range(128)
With fix we could see both:
root@node-4:~# neutron net-list

Small comment: in openrc file LC_ALL=C is not present, but we need to unset in manually by "unset LC_ALL=C" because SSH forwards it from server to master node and then to controller.
