Documentation doesn't explain that path and query are omitted from the call to `call`

When implementing a https://docs.rs/hyper/0.13.10/hyper/client/connect/index.html the documentation says:

A "connector" is a Service that takes a Uri destination, and its Response is some type implementing AsyncRead, AsyncWrite, and Connection.

This is a bit misleading -- specifically, the Uri that it receives is not the Uri that the request is for -- the path and query part appear to be stripped, leaving just the schema and the authority.

I think this is because, for connection pooling, only the scheme and authority are considered as part of the hash key.

Good point, would be worth putting in the documentation!
