/**
* Associate a pre-existing LDAP DB instance with a new DNS zone.
*
* @warning This is a hack.
*
* Normally, an empty database is created by dns_db_create() call during
* dns_zone_load().
*
* In our case, we need to create and populate databases on-the-fly
* as we process data from LDAP.
* We create an empty LDAP DB (which encapsulates internal RBT DB)
* for each zone when the zone is being added to zone_register.
*
* The database in zone register is modified on-the-fly and subsequent
* dns_db_create() call associates this populated database with the DNS zone.
*
* This allows us to call dns_zone_load() later when all the data are in place,
* so dns_zone_load() can be postponed until synchronization state sync_finish
* is reached.
*
* @param[in] argv [0] is database instance name
