Fix storage driver flag to show all the registered drivers as
options. Result:
```
-storage_driver driver
storage driver to use. Data is always cached shortly
in memory, this controls where data is pushed besides
the local cache. Empty means none. Options are:
<empty>, bigquery, elasticsearch, influxdb, kafka,
redis, statsd, stdout
