Installers now pass a single CustodiaInstance object around, instead of creating new instances on demand. In case of replica promotion with CA, the instance gets all secrets from a master with CA present. Before, an installer created multiple instances and may have requested CA key material from a different machine than DM password hash. In case of Domain Level 1 and replica promotion, the CustodiaInstance no longer adds the keys to the local instance and waits for replication to other replica. Instead the installer directly uploads the new public keys to the remote 389-DS instance. Without promotion, new Custodia public keys are still added to local 389-DS over LDAPI.
