Tomasz Grabiec cd9955d2ce lsa: Reclaim 1 segment by default ...

Reclaiming many segments was observed to cause up to multi-ms
latency. With the new setting, the latency of reclamation cycle with
full segments (worst case mode) is below 1ms.

I saw no decrease in throughput compared to the step of 16 segments in
neither of these modes:
  - full segments, reclaim by random evicition
  - sparse segments (3% occupancy), reclaim by compaction and no eviction

Fixes #1274.
