The patch removes the ruby_fs.py file. The functionality is being moved to fs.py. This would being ruby fs simulations in line with how ruby se simulations are started (using --ruby option). The alpha fs config functions are being combined for classing and ruby memory systems. This required renaming the piobus in ruby to iobus. So, we will have stats being renamed in the stats file for ruby fs regression.
