Set QPID_HOST parameter to better support multi-node mode

the Qpid clients need the hostname of the potentially
remote Qpid server in order to permit the necessary RPC
communication between components.

Fixes bug #1196521

devstack: Add paths specific to XenServer Core

 * XenServer Core keeps its Xapi plugins in a different path to XenServer,
   in order to comply with the Filesystem Hierarchy Standard.

 * XenServer Core mounts devices under /dev/xen/blktap-2 in dom0,
   whereas XenServer mounts them under /dev/sm.
