Config to exclude class prefix from serialize-messages, #24273 (#27517)

* Config to exclude class prefix from serialize-messages, #24273

* Adding no-serialization-verification-needed-class-prefix, with "akka." included
  by default
* This is important now when we disable Java serialization by default.
  There will be many complaints about Akka internal classes that are not marked with
  NoSerializationVerificationNeeded, and we can't really sprinkle that everywhere.
* Not removing NoSerializationVerificationNeeded usage in Akka classes because that
  may break bin compat, even though it's needed any more.

* fix DisabledJavaSerializerWarningSpec
