Usage: /usr/bin/rbd-replay --conf=<config_file> <replay_file>
Options:
  -p, --pool-name <pool>          Name of the pool to use.  Default: rbd
  --latency-multiplier <float>    Multiplies inter-request latencies.  Default: 1
  --read-only                     Only perform non-destructive operations.
  --map-image <rule>              Add a rule to map image names in the trace to
                                  image names in the replay cluster.
  --dump-perf-counters            *Experimental*
                                  Dump performance counters to standard out before
                                  an image is closed. Performance counters may be dumped
                                  multiple times if multiple images are closed, or if
                                  the same image is opened and closed multiple times.
                                  Performance counters and their meaning may change between
                                  versions.

Image mapping rules:
A rule of image1@snap1=image2@snap2 would map snap1 of image1 to snap2 of
image2.
