Description of problem:

Right now upstream bind-dyndb-ldap supports persistent search only for zones.
That allows the name server to immediately read new/modified DNS zones when
they are added/removed from LDAP.

We would need to extend this feature also for DNS records so that records in
given zone (for example A record for foo.example.com in zone example.com) or
records directly in zone (for example MX record directly in zone example.com)
are immediately loaded when they are changed in LDAP.

Actual results:
Record is changed but its resolvable after the record validity expires.

Expected results:
Changed record is immediately res
