Add unit tests for "hypervisor list" command

There is no unit tests for "hypervisor" command. This patch
introudces a new class FakeHypervisor to fake one or more
hypervisors, and a base class TestHypervisor. Also adds
hypervisors mock to fake compute client.

And also, this patch adds unit tests for "hypervisor list"
command.
