Description

Currently the header of rename_stats is like:

rename_stats: 
-
  snapshot_time: 1234567890.123456789
  start_time:    1234567880.987654321
  elapsed_time:  9.135802468

Change it to:

rename_stats: 
- snapshot_time: 1234567890.123456789
- start_time:    1234567880.987654321
- elapsed_time:  9.135802468

Both are valid YAML but the latter is more friendly to human.
