When memory footprint test is over it prints total size taken by row
cache, memtable and sstables as well as individual objects' sizes. It's
also nice to know the details on the row-cache's individual objects.
This patch extends the printing with total size of allocated object
types according to migrator_fn types.
Sample output:
mutation footprint:
- in cache: 11040928
- in memtable: 9142424
- in sstable:
mc: 2160000
md: 2160000
me: 2160000

- canonical: 827
