fstests: set up iSCSI target on NFS server before test nodes

The iSCSI target service must be running on the NFS server
before test nodes attempt to connect as initiators for pNFS
block layout testing.

Add a play to the fstests playbook that sets up the iSCSI
target on the NFS server when pNFS is enabled. This ensures
the target is listening on port 3260 before initiators try
to discover and connect.
