Allow sending parallel gRPC requests

[sudheesh001]

Hi Team,

This is a feature request, the parallec library works beautifully for making parallel requests and is blazing fast. However, It'd be really nice to enable a way to easily send grpc calls to a given list of (host, port) pairs. Its currently quite cumbersome for a developer making grpc requests to handle the threads and make the requests to the list of host, port pairs

@sudheesh001 Hi Sudheesh, thanks for the kind words and suggestion. It is a part of future work and just lack of resources for now. Feel free to submit a pull request and I can review that
