Bug 31969: Add background queue options to cleanup_database

This patch adds background queue options to cleanup_database.pl to allow
for purging completed background jobs.

--bg-jobs DAYS Purge all finished background jobs this many days old. Defaults to 1 if no DAYS provided.
--bg-type TYPE What type of background job to purge. Defaults to "update_elastic_index" if omitted
               Specifying "all" will purge all types. Repeatable.

To test:
 1 - Enable elastic search in Koha
 2 - perl misc/maintenance/touch_all_items.pl
 3 - Generate an number of diffrent types of bg-jobs (eg batch_hold_cancel,
     batch_biblio_record_deletion, batch_item_record_deletion)
 4 - Check db and note there are a bunch of diffrent jobs
 5 - Update to make them old
     UPDATE background_jobs SET ended_on = '2022-10-01 00:00:00', status='finished'
 6 - perl misc/cronjobs/cleanup_database.pl
 7 - Note bg-jobs entry shows in help
 8 - perl misc/cronjobs/cleanup_database.pl --bg-jobs 1 -v
 9 - Note that elasticqueue would have been cleared
10 - perl misc/cronjobs/cleanup_database.pl --bg-jobs 1 -v --confirm
11 - Note that number of entries deleted is reported
12 - Attempt to clear other job types, including "all" eg
     perl misc/cronjobs/cleanup_database.pl --bg-jobs 1 --bg-type batch_item_record_deletion  -v --confirm
     perl misc/cronjobs/cleanup_database.pl --bg-jobs 1 --bg-type all  -v --confirm
13 - Confirm in staff interface that jobs are gone:
     http://localhost:8081/cgi-bin/koha/admin/background_jobs.pl
     (Uncheck 'Current jobs only')
