Marcel de Rooy 73c5cb3277 Bug 7240: Cleaning up import tables and action_logs
This patch lets cleanup_database also purge older records from the (five) import tables and the action_logs table.
Two new command line parameters are introduced: --import and --logs.
If no number of days is specified for --zebraqueue, --import or --logs, it defaults to 30 days, 60 days resp. 180 days.
I did not add a default for --sessdays, because this parameter cannot be seen separately from parameter --sessions.

Adds new parameters and code, does not change existing behaviour

--sessions purge the sessions table. If you use this while users
are logged into Koha, they will have to reconnect.
--sessdays DAYS purge only sessions older than DAYS days.
-v --verbose will cause the script to give you a bit more information
about the run.
--zebraqueue DAYS purge completed zebraqueue entries older than DAYS days.
Defaults to 30 days if no days specified.
-m --mail purge the mail queue.
--merged purged completed entries from need_merge_authorities.
--import DAYS purge records from import tables older than DAYS days.
Defaults to 60 days if no days specified.
--logs DAYS purge entries from action_logs older than DAYS days.
Defaults to 180 days if no days specified.
