Subject: [PATCH] Add IPv6 support to openrc files

Assumes devstack was configured with SERVICE_IP_VERSION in
local.conf

SERVICE_IP_VERSION is stored in .stackenv and checked in
openrc. If SERVICE_IP_VERSION is set to 6, openrc will use
IPv6.

NOTE: At first, I added a '-6' option to the openrc call
which would set the HOSTS accordingly. I then simplified
the code by saving SERVICE_IP_VERSION to the .stackenv file
which is sourced by openrc. After that, I simplified the
code even more by removing an extra, unnecessary, variable.
