Use OkHttpHttpSender to send a list of objects in JSON format.

Hi OTel friends, it looks like when the OkHttpHttpSender is configured to exportAsJson, the Marshaler delegate JsonSerializer to serialize the object, and it always enclose the message with { and }. Do we support serializing lists, i.e. enclosing the body with [ and ]?

Followup: Would you open to remove the final keyword of the writeJsonTo methods so that this behavior is customizable when using OkHttpHttpSender to send JSON objects?

exportAsJson is not part of the public API, so we don't document or make guarantees about its behavior.

Everywhere we do JSON serialization of OTLP payloads, we follow the OTLP spec.

I see, the sender deals with OTLP request (and response) so it doesn't make much sense to make it customizable at this level. Thanks!
