Michał Chojnowski 1cfce430f1 replica/table: keep track of total pre-compression file size ...

Every table and sstable set keeps track of the total file size
of contained sstables.

Due to a feature request, we also want to keep track of the hypothetical
file size if Data files were uncompressed, to add a metric that
shows the compression ratio of sstables.

We achieve this by replacing the relevant `uint_64 bytes_on_disk`
counters everywhere with a struct that contains both the actual
(post-compression) size and the hypothetical pre-compression size.

This patch isn't supposed to change any observable behavior.
In the next patch, we will use these changes to add a new metric.
