When installing Openstack Newton as part of the
https://wiki.openstack.org/wiki/Documentation/NewtonDocTesting python-cinder
cannot be installed due to missing dependencies:
nothing provides python-paramiko >= 2.0 needed by
python-cinder-9.0.0.0~b3~dev100-1.1.noarch

This is due to old packages in opensuse preventing paramiko 2.0 from building: 
https://build.opensuse.org/package/live_build_log/Cloud:OpenStack:Master/python-paramiko/openSUSE_Leap_42.1/x86_64


I believe the issue to be htat is using an old version of python-cryptography
(1.0-5.4 ) and at least version 1.1 should be there as it adds support for
Elliptic Curve Diffie-Hellman:
https://cryptography.io/en/latest/changelog/#id15


Reproducible: Always

Steps to Reproduce:
1. Add the openstack repos: zypper addrepo -f
obs://Cloud:OpenStack:Newton/openSUSE_Leap_42.1 Master
2. Try to install python-cinder: zypper in python-cinder
Actual Results:  
python-cinder fails to install due to missing dependencies

Expected Results:  
python-cinder installs
