John Ferlan 0623945c40 tests: Add createVHBAByStoragePool-by-parent to fchosttest 
Add a new test to fchosttest in order to test creation of our vHBA
via the Storage Pool logic.  Unlike the real code, we cannot yet use
the virVHBA* API's because they (currently) traverse the file system
in order to get the parent vport capable scsi_host. Besides there's
no "real" NPIV device here - so we have to take some liberties, at
least for now.

Instead, we'll follow the node device tests partially in order to
create and destroy the vHBA with the test node devices.
