Rename ldap_sync_time to be more representative of what it actually does
ZD Ticket: https://gitlab.zendesk.com/agent/tickets/89287
A customer tried to use ldap_sync_time
to change how often LDAP syncs users. They actually want to use:
ldap_sync_worker_cron
as defined here: https://docs.gitlab.com/ee/administration/auth/ldap.html#adjusting-ldap-user-and-group-sync-schedules
In a pairing session, Support deduced that this should probably be called "ldap_authorization_check_time" or something similar.
Support would like to fix this as a "Support Engineering Coding Initiative".
