[IMP] l10n_ar_tax: add monthly cron to clean old padron files.

1) Add _cron_clean_old_padron_files method to delete old records.
2) Create cron in data (noupdate="1") with monthly execution.
3) Add test_cron_deletes_only_old_padrons test ( odoo-argentina/l10n_ar_tax/tests/test_padron_cleanup_cron.py ) to verify old records are deleted after cron execution.
