A short delay is required between starting up a primary and
secondary process with DPDK depending on what the secondary
depends on wrt the primary. As the SPDK sample apps are not
designed to be dependent on each other, when we use them
as primary/secondary in test scripts with no deterministic
synchronization, it is possible for one ore more to hang
resulting in DPDK fatal init failures. Often times this would
show up as a failure to get hugepages in vtophys
A related fix, same failing signature in the same test script,
is also included here where the stub app, which is designed
to act as primary in certain sections of the test script, was
being killed by the test script but the next primary app was
coming up before the process was dead and coming up as a
secondary. A wait was added to assure that the stub process is
gone before the next app tries to start.
