Remove IsLocal

[Tratcher]

We keep getting questions like this: aspnet/Hosting#570 (comment)

Environments are the correct way to handle these scenarios most of the time.

We should remove IsLocal, and possibly replace it with an extension method that just returns RemoteIP.Equals(LocalIP).

Yea, kill it IMO

If we add it back as an extension method won't be in the same place? It seems like an OK thing to remove from ConnectionInfo though.

Current recommendation is to remove it without adding an extension.

[muratg]

Yup, no extension method. This was redundant anyway.
