----------------------------------------------------

             Summary: Connector plugins config endpoint does not include Common 
configs
                 Key: KAFKA-14843
                 URL: https://issues.apache.org/jira/browse/KAFKA-14843
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
    Affects Versions: 3.2.0
            Reporter: Jorge Esteban Quilcate Otoya


Connector plugins GET config endpoint introduced in 
[https://cwiki.apache.org/confluence/display/KAFKA/KIP-769%3A+Connect+APIs+to+list+all+connector+plugins+and+retrieve+their+configuration+definitions|https://cwiki.apache.org/confluence/display/KAFKA/KIP-769%3A+Connect+APIs+to+list+all+connector+plugins+and+retrieve+their+configuration+definitions,]
 allows to get plugin configuration from the rest endpoint.

This configuration only includes the plugin configuration, but not the base 
configuration of the Sink/Source Connector.

For instance, when validating the configuration of a plugin, _all_ configs are 
returned:

```

curl -s 
$CONNECT_URL/connector-plugins/io.aiven.kafka.connect.http.HttpSinkConnector/config
 | jq -r '.[].name' | sort -u | wc -l     
21

curl -s 
$CONNECT_URL/connector-plugins/io.aiven.kafka.connect.http.HttpSinkConnector/config/validate
 -XPUT -H 'Content-type: application/json' --data "\{\"connector.class\": 
\"io.aiven.kafka.connect.http.HttpSinkConnector\", \"topics\": 
\"example-topic-name\"}" | jq -r '.configs[].definition.name' | sort -u | wc -l
39

```

and the missing configs are all from base config:

```

diff validate.txt config.txt

< config.action.reload
< connector.class
< errors.deadletterqueue.context.headers.enable
< errors.deadletterqueue.topic.name
< errors.deadletterqueue.topic.replication.factor
< errors.log.enable
< errors.log.include.messages
< errors.retry.delay.max.ms
< errors.retry.timeout

< key.converter
26d14
< name
33d20
< predicates
35,39d21
< tasks.max
< topics
< topics.regex
< transforms
< value.converter

```

Would be great to get the base configs from the same endpoint as well, so we 
could rely on it instead of using the validate endpoint to get all configs.
