Bug 34924: Add Koha::Checkout->attempt_auto_renew

This patch moves the actual renewal out of the auto_renewals cronjob script and into the object and adds tests. The logic for notices is still handled in the script.

To test:
1 - prove -v t/db_dependent/Koha/Checkouts.t
2 - Add a circ rule with auto_renew checked
3 - Checkout an item to a patron and set due date in the past
4 - Checkout an item to a patron and set due date in the future
5 - perl misc/cronjobs/automatic_renewals.pl -v
6 - Confirm one would be renewed and the other is too_soon
7 - perl misc/cronjobs/automatic_renewals.pl -v --confirm
8 - Confirm the expected issue is successfully renewed
