Functionality Added or Changed

• Vinyl: a new force_recovery mode to recover broken disk files
  Use box.cfg { force_recovery = true } is useful to recover corrupted data files after hardware issues or power outages.
  vinyl: support force_recovery tarantool#2253

• Vinyl: index options can be changed on the fly without rebuild.
  Now page_size, run_size_ratio, run_count_per_level and bloom_fpr index options can be dynamically changed via index:alter(). The changes take effect in newly created data files only.
  vinyl: page_size, run_size_ratio, run_count_per_level, bloom_fpr: change without space rebuild tarantool#2109

• Vinyl: improve box.info.vinyl() and index:info() output
