Subject: [PATCH] Drop support for "kvmibm" distro

The IBM hypervisor distro "KVM for IBM z Systems" gets discontiued,
like announced in March 2017 [1]. The key dates are:

* 03/2017: announcement
* 08/2017: the last day to order (EOM)
* 03/2018: the End of Service (EOL)

As the CI which tests OpenStack with KVM on IBM Z doesn't rely on this
distro anymore and EOM has reached, we remove the Devstack support for
this distro.

This basically reverts commit a5ea08b of Dec 2015.

NOTE: This doesn't affect other distros which have KVM on Z support.
