trivial: fix benchmark data generation script

While trying to create some fake data, I realized the randomizer
code was not running, nor were changes being committed, and largely
the code was still patterned on ipmi, when really we should be
patterning on fake. Also drops the number of nodes to create to 5000,
instead of 10,000, as we're ultimately going to create a fairly unhappy
fake ironic database with this model.

Using the fake interface *and* fake config, provides us an easy
path to begin to benchmark drastic changes to the conductor model
as part of removing eventlet.
