Review Comment:
I do not think the order is fixed even if you change the order in the param
list, unless `@JsonPropertyOrder` is declared.
It kind of reminds me of the clarity of the payload. See the example below.
It feels unclear. Because the fields in node settings response payload were
only about the cassandra node below. Now, we have a field about sidecar, that
is sitting next to the cassandra fields at the _same_ level.
We certainly cannot change the schema of the existing fields. I guess you do
not want to add an extra endpoint just for sidecar.
What do you think about adding a sidecar json object, that includes the
sidecar version and other related settings to be added in the future?
```json
{
"partitioner": "Murmur3Partitioner",
"releaseVersion": "4.0",
"sidecarVersion": "1.0"
}
```
The alternative,
```java
{
"partitioner": "Murmur3Partitioner",
"releaseVersion": "4.0",
"sidecar": {
"version": "1.0"
}
}
```
