Review Comment:
it seems `AdminListenersValidator` could be replaced by
`ConfigDef.ValidList.anyNonDuplicateValues(true, true)`, right?

Review Comment:
It seems this method was previously named `inNonEmpty`. Could you update the
error message to reflect that?

Review Comment:
I'm not sure what the rule is for changing the default value from `String`
to `List<String>`. For example, the default value type of `metric.reporters` is
still `String` rather than `List<String>`

Review Comment:
Do we really need `listeners.stream().collect(Collectors.joining(","))`? the
default implementation of `toString` should work fine in this case.

Should we align the behavior with `DefaultSslEngineFactory` to set it only
if `sslCipherSuites` is not empty?

@m1a2st renaming it does not cover the test case of "remaining instances are
