TypeScript client test to manage RPC server #367
Description
For reference, server_test.cpp can optionally startup the C++ RPC server when it starts up, then shutdown the server when it's done. Currently the TS client relies on the server to already be up and listening when it comes up. This issue is to enhance the TS client so that it can manage the lifetime of the RPC server (bringing it up and down as appropriate on a configurable port or Unix domain socket). Ideally the choice of RPC server (e.g., the C++ reference server or the Scala production server) should also be configurable. This Enhancement will streamline integrations and CI testing.
