SUBDATE syntax error with the where clause from example config

[David Moreau Simard]

Hi and thanks for osarchiver 🎉

Writing this down in case someone else bumps into this.

The example config has the following line:
where=${deleted_column} <= SUBDATE({now}, INTERVAL ${retention})

However this yields a syntax error:

2020-06-01 20:27:29,725 DEBUG: Executing SQL command: 'SELECT * FROM `nova`.`agent_builds` WHERE id > '0' AND deleted_at <= SUBDATE(2020-06-01 20:27:29, INTERVAL 1 MONTH) LIMIT 1000'
2020-06-01 20:27:29,725 ERROR: SQL error: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '20:27:29, INTERVAL 1 MONTH) LIMIT 1000' at line 1")

From the mariadb docs for subdate, the syntax requires the date to be inbetween single quotes: https://mariadb.com/kb/en/subdate/

So the correct line would actually be:
where=${deleted_column} <= SUBDATE('{now}', INTERVAL ${retention})

Hello @dmsimard,

Thanks for pointing me this case. I will update the example config file accordingly.
