In the ideal future, users will have one or more gopls instances, each serving potentially many LSP clients. In order to have any hope of navigating this web, clients and servers must know about eachother. To allow for such an exchange of information, this CL adds an additional handler layer to the serving configured in the lsprpc package. For now, forwarders just use this layer to execute a handshake with the LSP server, communicating the location of their logs and debug addresses.
