neutron-ha-tool: add os_region_name parameter

This adds an os_region_name parameter which gets passed to
the neutron-ha-tool Python script, in order to support this
upstream change to the latter:

  openstack-archive/cookbook-openstack-network@58f12c5

This was rescued from the unmerged pull request on the old repository:

  madkiss/openstack-resource-agents#21

See also crowbar/barclamp-neutron#217

(cherry picked from commit 7fa9b868e30143bc26e09b9db8ace41c5efeb49b)
