Title: Fixing bug in system_manager.alter_column_family() where default_validation_class is ignored

I ran into a bug where it was impossible to update the default_validation_class using the alter_column_family command - the parameter is there but not used in the body.

I added a simple test case to show the failure. It might be worth writing something more comprehensive to ensure other parameters are being set properly.
