>          Issue Type: Bug
>          Components: config
>    Affects Versions: 2.3.0

>            Priority: Major
>             Fix For: 2.3.1

> In add/alter new configs for DynamicConfigs it does not go through the KafkaConfig
> eg: bin/kafka-configs --bootstrap-server localhost:9092 --entity-type brokers --entity-name 0 --alter --add-config log.cleaner.threads=2
> However the bootstrap-server localhost is parsed through the kafkaConfig to create the adminClient but not the log.cleaner.thread. 
> As the configs are not parsed using the KafkaConfig if we pass variables in configs they are bot resolved at run time.
> In order to resolve the variables in alterConfig/addConfigs flow we need to parse the new configs  using KafkaConfig before they are parsed.
