Add sample zipf distribution randomizer

Instead of just doing purely random IO where each block is
touched exactly (or close to, depending on random map) once,
add a zipf distribution scheme where a selectable theta

rdma ioengine improvement

1) Use fio shipped reentrant and thread-safe rand to replace buggy rand().
2) Add a pause time period before client start committing IOs.
In SEND/RECV test, it's a good practice to setup the iodepth of
of the RECV side deeper than that of the SEND side to
avoid RNR (receiver not ready) error. The
SEND side may send so many unsolicited message before
RECV side commits sufficient recv buffers into recv queue.
This may lead to RNR error. Here, SEND side pauses for a while
during which RECV side commits sufficient recv buffers.
3) Fix server thread hanging bug.
For RDMA WRITE/READ test, No IO bytes are accumulated in server side
during test. Server thread indicates its task completion by changing
