Calle Wilund 560d3c17f0 commitlog: Add keeping track of approximate lowest GC clock for CF entries ...

Adds a lowest timestamp of GC clock whenever a CF is added to a CL segment
first. Because GC clock is wall clock time and only connected to TTL (not
cell/row timestamps), this gives a fairly accurate view of GC low bounds
per segment.

Includes of course a function to get the all-segment lowest per CF.
