Added the options to Options.py for FS mode with backward compatibility. It is good to provide an option to specify the disk image and the memory size from command line since a lot of disk images are created to support different benchmark suites as well as per user needs. Change in program also leads to change in memory requirements. These options provide the interface to provide both disk image and memory size from the command line and gives more flexibility.
