In some rare cases it is possible for a row in Cassandra for
metrics to have no value for metric_id or created_at, though
they may still have updated_at and the other required columns.
This tool is for recreating the metric_id from the other required
columns.
An additional 'persister-check-missing-metric-id.py' tool is
provided which can be run to see if there are missing metric-id
values that need to be recreated.
Please see the README.rst for usage directions.
