reftable: make the compaction factor configurable
When auto-compacting, the reftable library packs references such that
the sizes of the tables form a geometric sequence. The factor for this
geometric sequence is hardcoded to 2 right now. We're about to expose
this as a config option though, so let's expose the factor via write
options.
