Add exception handling in server for when gRPC client closes stream

[namannandan]

Description

Based on fix demonstrated in https://github.com/pytorch/serve/pull/3267 with additional exception handling.

The following cases are handled:

1. If the stream has already been closed by the client, we won't attempt to send a response since we check to see if the stream is still open before attempting to send a response.
2. If the stream gets closed after we check to see if the stream is open but before we attempt to send a response, then the exception IllegalStateException is caught and handled. This should prevent the worker from dying.
3. Extend the above two fixes to management and OIP requests as well.

Fixes #3087
