Jim Harris bef22f45e7 bdevperf: add -F option for zipf distribution 
Currently this will only support a global setting
that must be set on the command line.  We can make
it per-job later, but will require adding float
support to the conf library.

Tested by running bdevperf with some malloc
bdevs.  Performance with low theta values (i.e. 0.2)
are almost identical to random w/o zipf.  But
higher zipf values start to show better performance,
because we get more hits on data that is already
in the CPU cache.
