Add zhmcclient to global-requirements

zhmcclient is a python binding for the IBM z Systems
ReST API in DPM (Dynamic Parition Manager) mode. zhmcclient is used
by nova-dpm [1] and networking-dpm [2].

Nova-dpm contains the dpm virt driver for nova compute. It uses
zhmcclient to CRUDL instances.

Networking-dpm contains a mechanism driver for the neutron server
and the dpm neutron l2 agent. It requires zhmcclient for networking
related configuration.

Neutron-l2 agent and nova-compute both run on the compute node. The
compute node can be any system that has access to the HMC ReST
API. This can be another z Systems, but also an x86 system.
The controller node (with the dpm neutron mechanism driver) does not
need access to zhmcclient.
