When deploy OpenStack on XenServer, we need install some XAPI plugins to dom0. This commit is to add utils for this purpose. If the os-xenapi version is different from the os-xenapi which contains the utils. Users can specify the version to the utils. So that the utils will download the right version of os-xenapi and copy plugins from there. Otherwise the utils will by default copy plugins from current installed packages.
