Support for batch with return_exceptions=True in RemoteRunnable

[rahermur]

I noticed a comment on the RemoteRunnable class in LangServe mentioning that batch with return_exceptions=True is not supported due to the lack of exception translation from the server:

    The following features are not supported:

    - `batch` with `return_exceptions=True` since we do not support exception
      translation from the server.

I was planning to use RemoteRunnable in batch mode, but when an exception occurs on the server, the entire batch is lost. I was wondering if this feature is on the roadmap for future development?

Do you have any work around for this issue ?
