contrib: Add tool for getting hsm stats
This is a very simple tool showing historgam of hsm calls in the given
log files.
Example:
$ hsmstat vdsm.log.1 vdsm.log.2
8515 getVolumeSize
2258 repoStats
51 getVolumeInfo
30 getVolumesList
19 teardownImage
...
We can get same output or better using logdb by writing some smart sql.
