[#541] Initialise gRPC on a separate thread (#545) 

MultiThreadedEventLoopGroup has been replaced with NIOTSEventLoopGroup. It's recommended by authors of grpc-swift especially for iOS platform and it allows us to set the priority because NIOTSEventLoopGroup is GCD based while MultiThreadedEventLoopGroup is pthread based.

[#541] Initialise gRPC on a separate thread (#545)

- priority increased to .default
