Tomasz Zawadzki 294e8a2fb6 bdevperf: do not start tests until RPC is sent
Starting with this patch it is possible to issue
"perform_tests" RPC to bdevperf application.
It will allow to configure the bdevs after startup,
but before starting the tests.

bdevperf in addition to usual cmd line params for tests,
need to be started with '-z' argument.
After that it is possible to start test using
'./bdevperf.py perform_tests'.
Tests can be issued multiple times in the same app run.

At this time the RPC does not take any arguments
for the tests. All are assumed to be set in
the command line.

This is series for adding RPC to bdevperf app.
