Stephen Finucane 970891a4ef Remove references to XenAPI driver
The XenAPI driver was removed during the Victoria release [1], while the
libvirt+xen driver has been removed in the Wallaby release [2]. Remove
references to Xen from DevStack since its all a no-op now.

[1] I42b302afbb1cfede7a0f7b16485a596cd70baf17
[2] I73305e82da5d8da548961b801a8e75fb0e8c4cf1
