Jim Harris 4b521e1720 app/stub: add a stub application to accelerate startup
Starting SPDK applications can take a long time due to
two factors:  DPDK memory initialization and NVMe
device initialization.

This stub application facilitates eliminating those
delays by leveraging DPDK's multi-process mode.  This
stub application acts as the primary process,
initializing DPDK as well as all NVMe devices bound
to userspace modules (uio/vfio).  Then another
SPDK process can be started using the same instance
ID, which will make that SPDK process a secondary
process of the stub and leverage the DPDK memory and
NVMe device initialization already performed by the
primary process.

To start this will be used to accelerate the iSCSI
system level tests (in test/iscsi_tgt) to significantly
reduce test time in the CI pool.
