Add SignalR to article comparing gRPC with HTTP APIs

[quicoli]

I believe a comparison with SignalR should also be done.

Totally my first thought when reading this. How does this (gRPC) differ/compare to SignalR?

[erikmf12]

I think the Alternative Framework Scenarios explains it pretty well. gRPC can't be used in browser senarios, as well as not being made for broadcasting messages.

Can I also bug about adding a comparison to WCF?

cc @Rick-Anderson - i think there's merit to an overall-encompassing messaging article in the ASP.NET docset, that would cover (and potentially provide guidance-per-scenario) for SignalR, gRPC, and so on. This feels like a broader-scoped goal than just for SignalR. Is this something your team would own or would that be something the PG would need to author and submit for review?
