Summary: Previously we could only select the CF on which to operate uniformly at random. This is a limitation, e.g., when testing universal compaction as all CFs would need to run full compaction at roughly the same time, which isn't realistic. This PR allows the user to specify the probability distribution for selecting CFs via the `--column_family_distribution` argument.
