foreign-menu: Check if storage domain is active for data center
This last patch of the series is where we actually check if the storage
domain is active in the data center the VM is associated with. It makes
use of g_strv_contains(), which is available only in glib version 2.44.
Compatibility code has been added if building against older versions
than required.
