Subject: [PATCH] ds: Support renaming of a replication plugin in 389-ds
IPA topology plugin depends on the replication plugin but
389-ds cannot handle older alias querying in the plugin
configuration with 'nsslapd-plugin-depends-on-named: ..' attribute
See https://github.com/389ds/389-ds-base/issues/4786 for details
Fixes: https://pagure.io/freeipa/issue/8799
