Description

When running a cleanup, it would be an advantage to anti-compact the smallest SSTables first, so that free disk space is gradually increased, so that larger sstables later on are more likely to successfully anti-compact.

In 0.6, currently Table.forceCleanup() just iterates the list of CFs in whatever order they come from tableMetadata.getColumnFamilies, which is just a keySet().

The code should be changed to sort the CFs, smallest first.
