tools: Add support for additional adapter parent options

Browse Source 
Add the ability to provide the adapter parent_wwnn and parent_wwpn
or the parent_fabric_wwn on the virsh command line for the pool
define/create as commands.  Update the virsh.pod description.

The parent optionally provides the name of the scsi_hostN node device to
be used for the vHBA.
Optionally provide the parent scsi_hostN node device to be used for the
vHBA either by parent name, parent_wwnn and parent_wwpn, or parent_fabric_wwn.
The parent name could change between reboots if the hardware environment
changes, so providing the parent_wwnn and parent_wwpn ensure usage of the
same physical HBA even if the scsi_hostN node device changes. Usage of the
parent_fabric_wwn allows a bit more flexibility to choose an HBA on the
same storage fabric in order to define the pool.
