Major overhaul of oftest command interface

Added tests/oft as top level executable

Support command line options for many config params

Use logging module for output

Got rid of oft_config.py; consolidate configuration in
oft (top level script) and pass around as a dictionary

Add oft_assert.py (the one useful piece of oft_config that
remained).
