Remove seed_hypervisor_libvirt_pool_capacity variable

This is ignored by Libvirt, so there is no need to pass it to the
libvirt-host role.

Note: omitting the capacity argument requires libvirt-host 1.3.1 or
later.

+    Removes the ``seed_hypervisor_libvirt_pool_capacity`` variable, which was
+    passed to Libvirt through the libvirt-host role when creating a storage
+    pool. This information is actually ignored by Libvirt, which gathers
+    capacity and other metadata from the storage backend. See `story 2007381
+    <https://storyboard.openstack.org/#!/story/2007381>`__ for details.
