Huan Xie f15fd26943 XenAPI: Move dom0 related operations to os-xenapi devstack plugin
When installing OpenStack via DevStack on XenServer, we need to
some preparation operations in dom0 which will refer the function
in devstack/tools/xen/functions file, but we are planning to move
the whole folder of tools/xen from devstack to os-xenapi, so it
this patch is to moving the dom0 related operation to os-xenapi
repo first.
